How to use this catalogue
This catalogue has been designed to enable users to access the information on the
whole product range in a straight-forward and logical manner. We are conscious
that the needs of our customers vary considerably and that, as our markets
continue to grow, many will be dealing with our systems and products for thefirst time.
Where product codes are already well known, the Product and Parts Locator at the
back of the catalogue will direct you to the pages relevant to each occurrence of a
particular item.
Each main product or system category has its own section. The sections are
arranged such that those detailing the simpler and smaller systems are at the
beginning. Exploded views of typical system configurations are given as a guide,
near to the front of each section.
In order to help you to ‘build’ a system, there are detailed Selection Charts at the
end of each section. Again, these are formatted in a logical manner, from mainhousings to incomers, outgoing devices to their accessories. Once a reasonable
level of familiarity with the TE Connectivity Dorman Smith product range has been
attained, complete circuit distribution systems can be readily configured directly
from the Selection Charts alone.
Following the main products sections, the Technical Data and Applications section
provides a high level of detail on both specific products and the principles of circuit
protection in general.
We trust you will find this catalogue informative, helpful and a quick and easy-to-
use tool whenever you need to configure MCB or MCCB distribution schemes.

Loadbank 200The Loadbank 200 metering facilities utilisestandard cableway extension enclosures with
optional door kits designed for panel mountedmeters. The size of the cableway will determine thecorresponding metering door kit. Where cable sizesexceed 70mm a recommendation would be toinclude two cableway extension enclosures tofacilitate easy wiring. The same could be advisedwhen fully populating an 18 way panel board withmeters. Current transformers and fuses can be DIN-rail mounted within the cableways using thefacilities provided within the optional door kits.

Loadbank 200/250The Loadbank 200/250 metering facilities utilisestandard cableway extension enclosures with
optional door kits designed for panel mountedmeters. The size of the cableway will determine thecorresponding metering door kit. Where cable sizesexceed 70mm a recommendation would be toinclude two cableway extension enclosures tofacilitate easy wiring. The same could be advisedwhen fully populating an 18 way panel board withmeters. Current transformers and fuses can be DIN-rail mounted within the cableways using thefacilities provided within the optional door kits.

Standard Terminology
The Harmonised Standard EN 60898 and the IEE Wiring Regulations BS 7671:2008contain references to a set of adopted standard terminology for the principaldevice parameters with regard to MCBs. This terminology is also embraced byother standards with regard to MCCBs and switches (EN60947-2 and EN 60947-3).
The standard terminology relates to the following parameters:
Rated Operational Voltage, Ue
Rated Insulation Voltage, Ui
Rated Current, InRated Short Circuit Capacity, Icn
Rated Service Short Circuit Breaking Capacity, Ics
Rated Ultimate Breaking capacity, Icu
Rated Voltage and Current
Rated Operational Voltage, Ue
The nominal voltage of the system should not exceed the stated value of Ue.For example: single-pole Ue = 230/400V, three-pole Ue = 400V.
The standardised values of 230V and 230/400V will progressively replace 240V,220/380V and 240/415V.
Rated Insulation Voltage, Ui
This is the voltage upon which the dielectric properties are based, using tests athigh voltage and mains frequency.
Unless otherwise stated, the rated insulation voltage is the value of the maximumrated voltage of the circuit breaker.
In no case shall the maximum rated voltage exceed the rated insulation voltage.
Rated Current, InThis is the current that the circuit breaker will carry continuously under specifiedconditions and upon which the time/current characteristics are based.
Unless otherwise stated, this value is based upon a reference ambient temperatureof 30 degrees Celsius.
EN 60898 Standard refers to the following terms:
Short Circuit Capacity
Rated Short Circuit Capacity, Icn
The calculated prospective fault current at the incoming terminals of thecircuit breaker should not exceed the stated value. For example: Icn = 10kA(marked 10000).
Service Short Circuit Breaking Capacity, Ics
This value is the maximum level of fault current operation, after which furtherservice of the device is assured without loss of performance. Note that there is norequirement for Ics to be marked on the device.
There is a proscribed relationship between Ics and Icn, as follows:For values of Icn up to 6000A Ics = Icn
For values of Icn 6000A to 10000A Ics = 0.75Icn (but with a minimum value of Ics = 6000A)For values of Icn above 10000A Ics = 0.5Icn (but with a minimum value of Ics = 7500A)

136
The EN 60947-2 and EN 60947-3 Standards also refer to the following terms.
Isolation SuitabilityThese define the requirements for the suitability of circuit breakers to performisolation duty by defining tests to which such units must comply. Conformingdevices must carry a standard symbol mark to show that they are suitable forisolation duty. For example, all Dorman Smith circuit breakers are so marked.
Utilisation CategoriesThe utilisation category of a circuit breaker is stated with reference to whetheror not it is specifically intended for discrimination by means of an intentional time
delay with respect to other circuit breakers in series on the load side undershort-circuit conditions.
Category AThis designates circuit breakers not specifically intended for selectivity with deviceson the load side. Circuit breakers will discriminate only up to certain fault levels,above which discrimination with devices on the load side cannot be guaranteed.
Category BThis designates circuit breakers specifically intended for selectivity with devices onthe load side. Such circuit breakers will incorporate some form of time delay.
EN 60947-2 recognises both a rated service and a rated ultimate short circuitbreaking capacity for both Category A and Category B circuit breakers.
Rated Service Breaking Capacity, Ics
In order to define this value, the circuit breakers under test must be subjected to atest sequence of:
Ics = o – t – co - t – co, where:o = opening time under fault conditionst = time interval before re-closing (not more than 3 minutes)c = closing operation on to a fault
After this test sequence, dielectric, terminal temperature and over-current tests areto be applied. The circuit breaker must meet certain test parameters to ensure thatthe device has not deteriorated in performance and can be put back into service.
Rated Ultimate Breaking capacity, Icu
In order to define this value, the circuit breakers under test must be subjected to a
test sequence of:
Icu = o – t– co.
After this test sequence, dielectric and over-current tests are to be applied.
The rated service breaking capacity (Ics) applies to short circuit faults that couldoccur in practice; whereas the ultimate short circuit capacity (Icu) is the maximumtheoretical fault value of the installation at the point of connection.
The standard defines the ratio between the two values. Ics will be shown as 25%,50%, 75% or 100% of its Icu value for Category A devices and 50%, 75% or 100% ofIcu for Category B devices.
A circuit breaker can remain in service after interrupting a short circuit up to its
rated value of Ics. However, where two or more faults occur between the Ics and Icuvalues, the capability of the device for continued operation must be verified.

Current Carrying andSwitching Devices
SwitchA switch is a mechanical device capable of making, carrying and breaking currentunder normal circuit conditions.
Disconnector (Isolator)A disconnector is a mechanical switching device that provides the function ofcircuit isolation.
Switch DisconnectorThis device combines the functionality of the two foregoing devices; it providesmaking, carrying, breaking and isolation of current within a circuit.
FusesFuses can be combined with any of the above devices in any physical order. Theinclusion of a fuse will add the functionality of short circuit protection, breaking thecircuit when the current flow is higher than that for which the circuit is rated.
Combination DevicesIn order to enhance circuit protection, switches and fuses are often combined
within a single device. The physical composition of the device can be identified bythe literal position of the words in its description. For example, the word ‘fuse’ atthe beginning of the device description identifies the fuse as forming part of themoving contact system, whereas placing it at the end of the description identifiesthe fuse as a static link.

Function
Fuse Combination Unit
Switching ApplicationsFor switching applications, the principal functions and capabilities include:
• Making and breaking operation
A switch must have the ability to make or break defined load and overloadcurrents at a rated operational voltage, for the useful life of the device.
• Short circuit action
The device must have the capability of handling short circuit current and/orthrough fault and/or fault making.
• Protection
The device must interrupt the circuit under overload and/or short circuitconditions.
• Isolation
To meet this requirement, the device must ensure disconnection of the supply forsafe downstream working. Facilities must be included for safety padlocking in the‘off’ position, together with positive indication of the contact position.
• Neutral switching
Where the neutral is reliably earthed, it is accepted that the neutral need not beswitched except in defined circumstances (e.g. the incoming switch disconnectorin a consumer unit) even though the Wiring Regulations (BS 7671:2008) class theneutral as a current carrying conductor.
In applications where the neutral cannot be confirmed as reliably earthed, the
neutral should be switched simultaneously with the phase(s) or alternativelyarranged to make before and break after the phase(s).

Utilisation CategoryThe utilisation category defines the basic circuit conditions and the switchingcapability of the device.
AC20/DC20 Connecting and disconnecting under ‘no load’.
Assumes all switching operations are carried out by othercapable devices before this device is operated.
AC21/DC21 Switching of resistive loads including moderate overloads. Suitable for purely resistive type loads.
Device can switch 150% of its rated current underfault conditions.
AC22/DC22 Switching of mixed resistive/inductive loads, including moderate overloads.
Suitable for mixed resistive/inductive loads.
Device can switch 300% of its rated current underfault conditions.
AC23/DC23 Switching of highly inductive loads.
These devices are provided principally as back-up to othermeans of switching, e.g. contactors. In the event of failure ofthe functional device, the AC23/DC23 device can safelyinterrupt a stalled motor current. Where devices are the
only means of controlling individual motors they shouldcomply with the requirements of Appendix A of theEN 60947-3 standard.
Category Circuit/application
Note: Switch disconnectors for AC21/DC21, AC22/DC22 and AC23/DC23 categoriesalso have to meet the requirements of AC20/DC20.
For specific and special applications such as switching of capacitors and tungstenlamps not covered by the EN 60947-3 standard, the manufacturer’s advice shouldbe sought.
Frequent and Infrequent UseThe designation ‘A’ or ‘B’ should be appended to utilisation categories to indicatethe suitability for frequent or infrequent use in service. The ‘Rule of Thumb’definition for full load current switching duty is:
Frequent (A): Up to five times a day for small devices, say up to 100 amps, andonce per week for larger devices.
Infrequent (B): One per week for the smaller devices and once per month for thelarger devices.

Miniature Circuit Breakers (MCBs)
In general terms, circuit breakers are thermal/magnetic electromechanical devicesthat provide current making, carrying and breaking functions and will ‘trip’ tointerrupt a circuit under abnormal conditions. MCBs are equipped with positivecontact indication flags: red indicates that the contact(s) are closed, greenindicates the open state. The contact(s) will open when tripped due to abnormalcircuit conditions or can be manually put into the open state by use of a handle.
These devices are used to provide protection and control of circuits againstoverload and short circuit conditions. Dorman Smith MCBs are supplied withvarious breaking capacities, particularly for ratings of 6kA and 10kA. The lowerrated devices are used typically in domestic installations, e.g. in consumer units,whereas the higher rated devices are suitable for a range of commercial andindustrial circuit protection applications.
The thermal and magnetic trip functions cater for different circuit abnormalities andoperate as follows:
Thermal Trip FunctionThe purpose of this form of protection is to interrupt the circuit upon sensing anoverload current. Typically, a bi-metallic strip is used such that it will deflect due todifferential expansion of the dissimilar metals in response to the heating effectcaused by the passage of current through it. The higher the current, the greater willbe the heating effect and the more the deflection. At a preset point the physicaldeflection will be sufficient to actuate the tripping mechanism, opening thecontact(s) and interrupting the circuit.
Magnetic Trip FunctionThe purpose of this form of tripping is to protect against the effects of short circuitfault currents. A wire coil or solenoid is used to provide this function, operating thetrip mechanism when the over-current reaches a preset magnitude. As the faultcurrent rapidly increases, the magnetic field also increases, energising the coil andmoving a cam that is part of the contact assembly to fully open the contact(s)thereby interrupting the circuit.
CharacteristicsMCBs are designed according to one of three distinct tripping characteristicsdesignated B, C or D. These designations relate to the magnetic trip setting and
indicate the multiple of nominal current that will be tolerated by the device beforetripping. The following table illustrates these characteristics with typical duties and
applications. The nominal rated current is denoted by the symbol In.
B 3-5 In Light duty, resistive loads
C 5-10 In Fluorescent lights, small motors, inductive loads
D 10-20 In Sodium lights, large motors (>3kW), largeinductive loads

MCB Tripping Characteristics – B, C and D Types
MCB Add-on Functions
Various accessories can be added to MCBs to enable remote access and signalling.For example, the contact status could be relayed to an alarm annunciator panelor SCADA system; the circuit breaker could be controlled also from theSCADA system.
Auxiliary ContactsRelaying of contact status can be achieved by the addition of an auxiliary contactand the contact form selected to suit the remote system input requirements.
Shunt TripThe addition of a shunt trip allows remote access to the breaker operation,permitting the supervisory system to manually trip the breaker. The shunt tripactuator is a coil that is normally de-energised in the closed (on) state. Whenactivated, the shunt trip will force the breaker to its ‘off’ state and the togglehandle and indicator flag will move to this corresponding position. Since the
‘fail-safe’ (i.e. non-powered) state of a shunt coil is with the breaker remainingclosed, this precludes its use for emergency stop purposes. The interconnectingwiring could be open-circuit, for example, and would therefore not allow the shuntto open the breaker when the remote emergency switch is closed.
Under-voltage ReleaseIf the supply voltage dropped to a low level and devices tripped, a dangeroussituation could exist if the devices were automatically reset. For example, motorscould suddenly restart or other operating machinery set in motion without warning.In the event that the mains voltage should drop significantly below its normaloperating range, typically to less than 50%, an under-voltage release will force thebreaker to its ‘off’ state and the toggle handle and indicator flag will move to thiscorresponding position. Only when the supply has returned to, typically, at least85% of normal operating voltage will the under-voltage release allow the breaker tobe closed.
If a break occurred in the interconnecting wiring in this case, the breaker would betripped, just as if the voltage had fallen below the threshold value. For this reason,it is advisable to include an alarm function when using a UVR function.
The tripping time for the thermal release is defined according to specific values ofapplied overload current, as follows:
1.13In >1h (In < 63A) >2h (In > 63A)
1.45In <1h (In < 63A) <2h (In > 63A)
2.55In 1s<t<60s (In < 32A) 1s<t<120s (In > 32A)

Energy Let-throughAn important facet of circuit protection devices is the extent to which they limit theamount of electrical energy they allow to pass through them. This applies to fusesas well as to circuit breakers.
When an electric current flows through a resistance for a certain time, energyis produced in the form of heat. This thermal effect can be measured usingthe formula:
I2 x R x t, to give a quantity in ‘Watt seconds’. The unit of measurement for energyis the Joule, which is equivalent to one Watt second.
For all practical purposes, the resistance is treated as constant and negligible;therefore the commonly accepted term for energy let-through of a device is I2tsince this will always be proportional to the true thermal effect. The I 2t term isreferred to as the Joule Integral since the results are expressed in integral form.
Under short-circuit fault conditions there is the potential for considerable energyto be let through by a circuit protection device. Knowledge of the energy let-through characteristics of circuit protection devices is useful for comparisonbetween different devices and also with regard to the selection of devices that arerequired to act in co-ordination to produce the levels of discrimination required forfault clearance.
The I2t characteristics of circuit breakers are depicted as curves, graphed againstvalues of prospective short-circuit current. These characteristics are relevant toboth MCBs and MCCBs as depicted in the following graphs.

Currents of low magnitude caused by unintentional ‘leakage’ paths to earth can causedeterioration within circuit wiring and components with the potential to create arapidly escalating situation that will permit the current to reach dangerous levels.
Special forms of circuit breakers are designed to use the detection of earth leakageor ‘residual’ current to limit the effects of this type of fault.
The generic term ‘residual current device’ is used to describe a range of circuitprotection devices that include the functions of sensing and measurement of aleakage current, with subsequent tripping when the magnitude of the residualcurrent reaches a preset level. The purpose of these devices is to protect humanlife, livestock, property and equipment against the escalation of earth fault currentsto destructive magnitudes.
Two forms of technology are commonly employed in the design of residual currentdevices; electromagnetic and electronic. In both cases, a current transformer isused and is arranged such that normal current flows in the phase and neutralconductors cancel each other to produce a zero balance. The presence of anyresidual current will create an out-of-balance that can be used to signal theactuation of a mechanism for circuit interruption.
In the electromagnetic type, a trip relay is used as the actuation device. The relay ispowered by the fault current and therefore requires no external power source.
With electronic devices internal signal amplification allows a much smaller currenttransformer to be used, reducing the physical size of the circuit breaker. In thiscase, however, the actuation power is derived from both the fault current and themains power. Also, a separate earth reference connection may be required toensure continuity of operation in the event that the mains neutral is lost.
Residual current devices are accorded a ‘sensitivity’ coding that indicates the levelof residual current that would cause a trip action. Commonly, the availablesensitivity ranges are 10mA, 30mA, 100mA and 300mA. In general, the 10mA and30mA devices are used to protect human life, the 100mA and 300mA devicesbeing applied to protect wiring, cabling and equipment.
The degree of electrocution that could take place when a fault arises depends uponthe combined effects of the magnitude and duration of current flow. For sensitivity
levels of 30mA and below, tripping must be instantaneous to protect human life.Longer periods of residual current flow can be tolerated by equipment and the tripaction may not necessarily be required to interrupt the circuit instantaneously.
Residual Current Circuit BreakerThe RCCB device combines the functions of a switch with those of a residualcurrent device. It is often used in place of an incoming switch disconnector withthe advantage that it functions also as a residual current protection device. Thedisadvantage, however, is that a residual fault will cause the device to operateinterrupting ALL downstream circuits even when these circuits remain in ahealthy state.
Note that an RCCB should not be used as the sole means to provide completeprotection. It has no overload or short circuit protection and must therefore befurther protected by an upstream device having these capabilities. Frequently, theRCCB is used in consumer units and distribution boards to protect sub-circuits in asplit load configuration. In these applications, the upstream back-up is provided bythe Regional Electricity Company’s local fuse.
Residual Current Breaker with Overload ProtectionThe RCBO combines the functions of an MCB with those of a residual currentdevice. It will therefore provide protection against overload, short circuit andearth leakage.

RCBOs and RCCBs – GeneralThese devices are furnished with a test pushbutton on the front face of themodule. Operation of this button will simulate the presence of a residual fault andthe test should be made frequently, say once per month, to assure continuedcorrect functionality of the device.
In addition to the range of sensitivities, RCBOs and RCCBs are available in twotypes, type AC and type A. These refer to the types of circuit for which thedevices are suitable.
Type AC: for use with residual sinusoidal ac, whether applied as a step or ramp.
Type A: for use with either residual sinusoidal ac or residual chopped (pulsating)dc, whether applied as a step or ramp.
A time delay facility may also be included, adjustable up to, typically, 50-70mS.This is denoted by ‘S’ included within the description and also marked on thedevice. This function is included in order to enable the device to be used aspart of a circuit device discrimination (or selectivity) arrangement. Without thetime delay, residual current circuit breakers cannot be easily used within adiscrimination scenario due to their inherent rapid tripping in response to residualcurrent detection.
Whereas RCBOs are single module width devices used in place of or alongsideMCBs in outgoing circuits, RCCBs are available in 2-pole and 4-pole forms and arereadily used in single phase and three phase distribution systems where they canfunction as either incoming or outgoing ways.
Due to their low levels of sensitivity RCCBs are generally equipped withsuppression filtering to avoid nuisance tripping that could be induced fromdisturbances in external or incoming circuits.

The operation and application of the MCCB is similar to that of the MCB, howeverthis device has the air-break mechanism contained within a moulded case housingmade from a very robust non-conducting material. Generally, MCCBs exhibit muchhigher breaking capacities and rated current than their smaller counterparts andcan be used to perform full isolation duty. Consequently, MCCBs are employed inboth incoming and outgoing circuits. MCCBs are constructed to a particular framesize and typically provide rated current in the range 16-1600A.
These devices can be equipped with adjustable thermal and magnetic trippingmechanisms to cater for overload and short circuit protection to meet therequirements for isolation and Category A discrimination duty. Dorman Smithelectronic MCCBs provide adjustable long, short and instantaneous trip functions,allowing more complex overall tripping characteristics to be configured, allowingthese devices to be used for isolation and Category B discrimination requirements.(Refer to page 136 for Category definitions).
Devices equipped with the full range of adjustable trips for long, short andinstantaneous durations are generally referred to as ‘LSI-MCCBs’ to distinguishthem from the L and I only versions employed for Category A devices.
The range of accessories that can be added to MCCBs is similar to that given in thesection dealing with MCBs, including shunt trips, under-voltage releases and variousforms of auxiliary contacts. The physical size of triple-pole and four-pole MCCBs
allows these accessories to be internally mounted, although there are somerestrictions with regard to combinations of these that can be co-mounted. Forexample, either a shunt trip or under-voltage release can be incorporated, but notboth. Also, due to the much larger physical size of these devices compared withMCBs, additional safety features normally include interphase barriers and terminalshrouds to provide IP2X ingress protection at the terminals.
The tripping operation of some MCCBs is different from that of MCBs in that there arethree distinct positions of the toggle or handle. Whereas MCBs are either ‘on’ or ‘off’,MCCBs have a central position when they are tripped. As a further safety feature, thecoloured flags indicating the ‘on’ and ‘off’ states are masked in the tripped state. Thebreaker can be reset only after it has been set into the fully ‘off’ state.
MCCBs are equipped with a test pushbutton that allows periodic testing of themechanical tripping mechanism. As in the case of a fault trip, the device must be
moved into the ‘off’ position before it can be reset following a test.
These devices conform to EN 60947-2 therefore the definitions that apply to someparameters differ from those of EN 60898 that apply to miniature circuit breakers.These differences are explained in the section covering Standard Terminology.
Motor Control ApplicationsThe MCCB is a viable means of providing motor control switching. However,MCCBs used for this type of application are often required to provide only shortcircuit protection, with the overload protection catered for by a separate thermalor electronic overload relay. For this reason, specifically designed ‘motor control’MCCBs are available upon request, with only the single tripping mechanism.
The range of circuit breakers for each frame size includes a basic switchdisconnector version, generally in both triple-pole and four-pole variants. Devices ofthis type are sometimes referred to as ‘non-auto MCCBs’.

In the context of power distribution schemes, the term ‘discrimination’ (sometimesreferred to as ‘selectivity’) describes a hierarchy of circuit devices that are arrangedsuch that a single upstream circuit breaker can fan out to several downstreamdevices to act in a co-ordinated fashion should a fault occur. Under fault conditions,only the upstream protective device closest to the fault should operate to clear thefault, leaving all other healthy circuits operable. This is especially important ininstallations where circuit failures could be life-threatening, such as in hospitals.
The concept of discrimination is similar to that of cascading, the prime differencebeing in the objectives of the application. Whereas discrimination is used to ensurecontinuity of supply to sub-circuits by limiting the disconnection to the faultedsub-circuit alone, cascading is used to buffer downstream protective devicesagainst the effects of high prospective short circuit currents.
In both cases, the protective devices are specifically selected to meet the criteriafor the type of co-ordination required.
When the selected devices are properly matched to fulfil the ideal discriminationprinciple described above, the co-ordinating devices are said to achieve ‘total’discrimination. In many practical installations, however, a partial discrimination maybe satisfactory for safe continuity of supply, with an added advantage of costsavings due to selecting a lower rated upstream circuit breaker.
Discrimination between two circuit breakers arranged in series may be based oneither current or time. Where the magnitude of the fault current is to be used asthe critical factor for selection, the co-ordination in this case is termed ‘currentdiscrimination’. Where the basis for selection is the duration over which theupstream device can withstand the fault current, the selection is to achieve ‘timediscrimination’. In some cases, time discrimination can be achieved by using anupstream device that has a built-in time delay.
Current Discrimination
In general, the basis for current discrimination is that the downstream protectivedevice will have a lower current rating than the upstream device. It should alsohave a lower instantaneous tripping point. The discrimination tables that followhighlight the consequential increase in discrimination level as the differential incurrent ratings between the devices increases.
Time DiscriminationDiscriminating by time between two devices in series relies on the operation of theupstream device being delayed at least until the downstream circuit breaker hastripped to clear the fault. The clearing time of the downstream device must be lessthan the time setting of the upstream device and the upstream device must also becapable of withstanding the fault current for the full duration of its time setting.There is generally no problem in achieving these conditions where the upstreamdevice is a Category B circuit breaker specifically designed for this type ofco-ordination duty.
Time/Current Characteristics
Comparison of the time/current characteristic graphs of the two devices proposedcan give a quick check on their suitability for co-ordination in both current and timediscrimination cases. Ideally, there should be no overlap of the respective curves toachieve total discrimination. If, however, the instantaneous portion of the curves do
intersect, a partial discrimination will be achieved at the current level projectedfrom the intersect point.
In the tables that follow, total discrimination is indicated by the letter ‘T’ inappropriate boxes. Total discrimination applies for all fault levels up to the lowerbreaking capacity of the two devices in co-ordination. Where a value is containedin any of the boxes, this indicates a partial discrimination of that value of currentlimit. If no discrimination is possible, this is shown by a dash symbol.

Note that ‘partial discrimination’ infers that, above the current limit value indicated, it is possible that both devices could trip,resulting in disconnection of other sub-circuits and loss of supply continuity to those areas of the distribution system.

Cascading is sometimes referred to as ‘back-up protection’. The technique ofcascading is used to allow circuit breakers with a breaking capacity lower than thevalue of prospective short-circuit current at the connection point to be used whenthese are positioned downstream of a current-limiting circuit breaker of higherbreaking capacity. The net result of this arrangement is that the downstreamdevice acquires an enhanced ’installed‘ breaking capacity, therefore a lessexpensive, lower breaking capacity breaker can be used.
The upstream circuit breaker must have the normally required breaking capacityfor its point of installation however, when combined with another circuit breakerdownstream, the two devices in series will be able to clear a larger fault. Forexample: if a 10A, 6kA MCB is place downstream of a YA frame MCCB rated at125A and 25kA, the MCB will have an installed breaking capacity of 14kA. Similarly,a 10A, 10kA MCB downstream of a YA frame MCCB rated at 250A and 25kA willhave an installed breaking capacity of 25kA.
It should be noted that the cascading technique is not limited to only two devicesin series. The important point is that it is the upstream device that is limiting thecurrent to a value that can be interrupted by the following device, so that thepattern of paired devices can be repeated many times in an hierarchy of devices.
The following tables give ‘installed breaking capacity’ values of downstream circuitbreakers for both the MCCB/MCB and MCCB/MCCB pairings of cascaded devices.
Note that all values shown are at 400V ac. The values for the installed breakingcapacities are given in kA.

Short-circuit Discrimination LevelsWhere a high prospective fault level exists at the MCB distribution point,discrimination at short-circuit levels should be considered. This will requirecomparison of the device I2t characteristics at the relevant prospective fault level.
Discrimination will be obtained at all fault levels for which the MCB total operatingI2t is lower than the pre-arcing I2t of the device closer to the supply.

The adequacy of sizing and rating of power distribution systems is important toensure supply continuity and safety in operation. A number of design parametersmust be taken into account in order to ensure that the supply and safetyrequirements are met. These include busbar ratings, short-circuit fault levels andcircuit utilisation.
Once the overall loading requirements have been established, and the supply
transformer selected, consideration of the circuit distribution systems follows.Distribution enclosures and their busbar systems are pre-tested to accepted normsof through-fault levels, typically 16kA, 25kA, 35kA, 50kA and 80kA. These short-circuit ratings alone will limit the choice of switchboard, panel board or distributionboard. The selection of the type and size of enclosure to be used will then dependupon the busbar current rating needed, together with availability of sufficientcircuit ways of the correct type for the circuits and sub-circuits to be supplied.
The busbar current rating is generally chosen to be sufficient to supply full load,plus some safety factor. For example, if the full load is expected to be 750 amps,an enclosure with a busbar rating of 800 amps may be selected. Once the busbarcurrent rating has been nominated, the incoming device for that group of circuitswill be matched to the rating. In the example cited, the incoming device wouldbe rated at 800 amps. More than one incoming device may be required to effectproper circuit protection and isolation, such as a switch disconnector in serieswith a thermal fuse. In this case, the fuse link will provide the protection and
the disconnector will permit isolation. Alternatively, a moulded case circuitbreaker (MCCB) employed as the incoming device will provide both protectionand isolation.
The size and type of circuits to be supplied will further refine the eventual choiceof distribution system. Automatic or manual circuit disconnection will point toan enclosure suitable for either circuit breakers or switch-fuse devices. If therequirement is for automatic disconnection, prospective fault levels at theconnection point may dictate that an MCCB must be used, rather than an MCB ofthe same current rating.
Finally, consideration is given to the degree of circuit utilisation capacity, oftenreferred to as ‘diversity’. Notwithstanding the limitations of the busbar system andthe matched protection provided by the incoming device, the outgoing circuit waysmay be configured with individual circuit protection devices having an aggregate
rated current capacity in excess of the rating of the incomer.
The basis for this approach is that it is often reasonable to assume that not allcircuits will be supplying their rated current at the same time. In this case, a‘diversity factor’ is applied during the design stage to give an overall servicecapacity for the outgoing circuits. The maximum current rating divided by thediversity factor will give the maximum aggregate ‘fitted’ current allowed. Thefollowing table lists the factors that may be applied subject to the number ofoutgoing circuits to be supplied.
Taking the example of a 400A panel board with 400A MCCB incomer and 6outgoing circuits, a diversity factor of 0.7 would allow outgoing MCCBs with anaggregate of 570A capacity to be installed. The individual circuits would beprotected at the level of current rating of each MCCB, with the incomer providingultimate protection at 400A. To allow for the possibility of future expansion of adistribution system, an allowance for 25% spare capacity is often included when
applying a diversity factor to the initial design.

The Prospective Short-circuit Current, or PSC, is the theoretical maximum faultcurrent that could exist at any point within a complete circuit distribution system.
The magnitude of the fault current at any particular point is calculated on the basis ofa ‘bolted’ (virtually permanent) fault path at that point and therefore assumes aconstant voltage, continuous current supply feeding the fault. Using this assumption,the PSC that could possibly exist at the bolted fault path would be limited only by the
sum of the circuit impedances of the complete current path, from high voltage feedto the supply transformer through to the bolted connection point. Since thisassumption cannot be fulfilled in practice (for example, the voltage will not remainconstant) the value of calculated PSC can never be exceeded in a practical scheme.
The foregoing commentary is particularly relevant to larger commercial and industrialnetworks, where many sub-systems are present and often, many sub-circuits withinthese. For more compact arrangements, such as domestic installations, where thedistribution scheme is contained within one or more consumer units, the situation ismuch simpler. The Regional Electricity Companies generally agree on a fixed faultlevel of 16kA at the local zone supply distribution point to one or more dwellings.Those dwellings that lie some distance from the zone origin point of the distributedsupply will have reduced PSC due to the higher impedance of the longer run ofservice cable. Consumer units should therefore have a minimum short-circuit rating of16kA. When an MCB trips, the combination of forced contact separation and rapid arcextinction produces a limiting effect on the fault current such that it will be
adequately handled within the normal 6kA breaking capacity of MCBs fitted todomestic installations.
PSC at the origin point –
In practice and with consideration of the total distribution network; the breakingcapacity of an individual circuit device would normally be less than that calculated forthe origin point of the scheme.
PSC at the connection point –
The breaking capacity of individual devices must be greater than (or at least equal to)the PSC at the specific point of their connection within a scheme. Conversely, wherethe circuit device breaking capacity is greater than the PSC at origin, there is no needfor further measurement or calculation in this regard.
The PSC at any particular connection point can be estimated, calculated, or
determined by measurement of the circuit impedance at that point. Measurement ofthe circuit impedances at all relevant connection points can be a laborious exercise;the calculation method is generally used since this can be readily carried out usingone of a number of available computer software packages.
PSC by calculation –The magnitude of the short-circuit current (rms value of the ac component) at theconnection point will depend upon:
• the PSC at the origin point.
• the total resistance in the circuit between the origin point and the relevant circuitreference point.
• whether the short-circuit condition is considered as phase-phase, phase-neutral orphase-earth.
The maximum PSC at the origin can be calculated from the following formula:
Supply transformer rating (kVA) x 100
√3 x secondary voltage x % transformer reactance
PSC by estimation –
To estimate the PSC, first calculate the total resistance in the LV circuit bydetermining the sizes and lengths of cables between the supply source and the pointunder consideration. Next, use the following table to find the cable resistances andsummate these to obtain the total resistance. Finally, use this value to read off theestimated PSC from the following graph.

PSC in a typical installation
Note that the values on the graph assume a symmetrical fault across the threephases. In a single circuit, for line-neutral faults, the cable resistance value given inthe table should be doubled.
The following values of PSC would be obtained at the various circuit points markedin the above diagram:
Point ‘A’ PSC = approximately 27kA
Point ‘B’ Two cables per phase, therefore halve the value.
Resistance from ‘A’ to ‘B’ = 0.3 Milli ohms
With reference to the graph PSC
can be assumed to be 25kA
Point ‘C’ Resistance from ‘A’ to ‘B’ = 0.3 Milli ohms
Resistance from ‘B’ to ‘C’ = 10.7 Milli ohms
Total circuit resistance ‘A’ to ‘C’ = 11.0 Milli ohms
With reference to the graph PSC
can be assumed to be 12kA
Point ‘D’ Resistance from ‘A’ to ‘B’ = 0.3 Milli ohms
Resistance from ‘B’ to ‘C’ = 10.7 Milli ohms
Resistance from ‘C’ to ‘D’ = 46.0 Milli ohms (Double the value for the 2-core cable)
Total circuit resistance ‘A’ to ‘D’ = 57.0 Milli ohms
With reference to the graph PSCcan be assumed to be 3kA

One of the most common means of protecting persons against the effects of highvoltages and currents is by insulating the wiring and components. Most earth faults occurwhen some part of the insulation has broken down, creating the possibility of causingelectric shock through indirect contact with the faulty circuit. The breakdown of insulationcan often cause all or part of an enclosure or frame to become ‘live’ by raising conductiveparts to a hazardous voltage level. Touching any of the exposed parts of the enclosure orframe would then be highly dangerous and would most likely cause an electric shock.
Whilst protective devices may open quickly to minimise the possibility of high currentsflowing for any significant length of time, additional measures are necessary to limit thepotential earth fault current at source. In some cases fault current limiting resistors orinductors may be installed at the transformer star point however, in all cases, it isimportant to ensure that the impedance of circuit conductors is kept to a minimum sothat the voltage developed under fault conditions will be restricted. The earth fault loopimpedance is denoted Zs and is an important circuit design parameter.
Circuit designs must always ensure that the magnitude of the fault current will besufficient to trip the over-current protective devices within acceptable times as stated inthe IEE Wiring Regulations. Circuit breakers are designed to trip and therefore disconnectfaulted circuits very quickly. The design value of tripping time is generally expressed in theform of a graph that maps current against time and any practical scheme can be checkedagainst this value to ascertain conformance with the requirements.
The fault current can be established very simply using Ohm’s law, as follows:
Fault current = Phase-to-earth voltage
Zs
Once this value is known, the corresponding tripping time can be read from the relevantdevice’s time/current characteristic graph and the result compared with that given withinthe Wiring Regulations. In general, the higher the nominal voltage of an installation, theshorter will be the required disconnection time. For fixed equipment installations, themaximum disconnection time is stated as 5 seconds, whereas it is 0.4 seconds forportable equipment. The Regulations define ‘portable’ as including fixed outlet socketsthat may be used to supply apparatus that is movable or portable when in use.
The following table illustrates the maximum Zs allowable for MCBs to achieve thespecified disconnection times.
Since the complete loop impedance is the sum of the individual impedances of thesupply transformer winding, circuit phase conductor and protective circuitconductor, the total may be higher than that specified for in-time disconnection forthe protection device proposed. In these cases, several solutions may be possibleto overcome or at least assist in achieving compliance.
• The supply cable may be replaced by one with greater cross sectional area
• The short-circuit tripping threshold of the device may be set to a lower value(if it is adjustable)
• A Residual Current Device could be used to replace the circuit breaker in question
The following tables indicate the maximum Zs for Dorman Smith’s range ofMCCBs. Using these tables obviates the need to determine the suitability of adevice by reference to its time/current characteristic graph.

The principle of separation applied to multi-cubicle switchboards and panel boardsis the achievement of a high degree of safety for equipment and people duringnormal operation and to promote safe working during commissioning and service.The resulting concept is one of functional separation and segregation of live partsof the system into sub-units by the use of barriers or partitions.
In general, separation should provide enhanced safety by:
• Protecting against contact with the live parts of adjacent functional units
• Preventing the passage of solid foreign bodies from one section of an assemblyto an adjacent one
Various elements of an assembly must be considered for separation fromneighbouring live sections, such as busbars, terminals and functional units. Thespecific form of their separation can be achieved in several ways according to theparticular application and the requirements for access for maintenance. Theminimum degree of protection to be achieved at each barrier or partition is to IP2Xas specified in the Ingress Protection standard EN 60529. Typically, this may include:
• PVC sleeving, wrapping or plastic coating of conductors
• Insulated terminal shrouds or PVC ‘boots’
• Rigid insulated barriers or partitions
• Compartments formed from earthed metal
• A device’s integral housing
There are several forms of separation, indicated by numbered category and sub-category; however the requirements for the degree of separation need to becarefully considered since the cost increases significantly with increased degree.
The principal categories are:
Form 1 – no separation
Typical applications are where the assembly is to be placed in a secure locationand where failure will cause little or no additional disruption to other areas beingsupplied by that particular assembly.
Form 2 – separation of busbars from functional units
Applications may be similar to those of Form 1 but where it is important that a faultneed not affect all functional units being supplied by the same busbar system.
Form 3 – separation of busbars from functional units and the functional units
from one another, but not their terminations
This form should be applied where it is important to provide protection frominternal live parts and where failure of functional units being supplied from thesame busbar would cause unacceptable disruption.
Form 4 – separation of busbars from functional units and the functional units
from one another, including their terminals
This form should be applied where it is important to provide protection frominternal live parts and where failure of functional units being supplied from the
same busbar would cause unacceptable disruption. Because all the terminations areseparated, it is possible to isolate and work on a single functional unit.
Dorman Smith ‘LF-type’ panel board systems are supplied in Form 2 as standard,with Form 4 versions achieved with simple conversion kits. However, otherseparation forms can be provided in special cases.
With the exception of Form 1, the other separation forms have sub-categories thatpermit permutations of the general form to be configured according to therequirements for specific applications and to allow the accommodation of differenttypes of protection method. The exact form of separation provided on an assemblyis a matter for agreement between the manufacturer and the end user.

The EN 60529 standard describes a system for classifying degrees of protectionagainst the ingress of foreign bodies and harmful liquids. It is intended that thisstandard is applied to enclosures of low voltage (LV) electrical equipment. Theclassification scheme comprises a designation prefixed by the upper case letters’IP‘, followed by two numerals.
The first numeral designates the degree of protection with regard to solid objects;
the second numeral indicates the degree of protection against the ingress of liquid.Compliance to the standard is intended to:
• protect persons against access to hazardous parts inside enclosures and protectthe equipment inside the enclosure against the ingress of solid foreign objects.
• protect the equipment inside the enclosure against harmful ingress of liquids.
For assemblies for indoor use where there is no requirement for the protectionagainst ingress of water, the following IP codes are preferred: IP00, IP2X, IP3X,IP4X, IP5X, IP6X.

The insulation distances between an MCCB and adjacent earthed metal parts andinsulators shown in the diagram below must be maintained to prevent arcing faultsoccurring due to conductive ionised gases. In cases where requirements differ fromthose illustrated here, the greater distance must be maintained. Where twodifferent YA frame devices are installed one above the other, the insulationdistance between the two should be as for the lower size of MCCB.
Exposed conductors must be insulated up to the barrier terminals. Interphasebarriers or terminal covers are recommended. However, if terminal covers are used,the exposed conductor must be insulated until it overlaps the terminal cover.
