To ensure a continuous supply of electrical power, certain installations are connected to two sources:b a normal source Nb a replacement source R used to supply the installation when the normal source is unavailable.

A source-changeover system switches the load between these two sources. It can be automated to manage transfers according to external conditions. A source-changeover system includes two or three circuit breakers or switch-disconnectors.

With Interpact INS, Compact NS and Masterpact NT and NW, new installation solutions are available to optimise the size of the switchboard and simplify installation.

Manual source-changeover systemThis is the most simple type. It is controlled manually by an operator and consequently the time required to switch from the normal to the replacement source can vary.A manual source-changeover system is made up of two or three mechanically interlocked manually-operated circuit breakers or switch-disconnectors.

Remote-operated source-changeover systemThis is the most commonly employed system for devices with high ratings (above 400 A). No human intervention is required. Transfer from the normal to the replacement source is controlled electrically.A remote-controlled source-changeover system is made up of two or three circuit breakers or switch-disconnectors linked by an electrical interlocking system that may have different configurations. In addition, a mechanical interlocking system protects against electrical malfunctions or incorrect manual operations.

Automatic source-changeover systemsAn automatic controller may be added to a remote-operated source-changeover system for automatic source control according to programmable operating modes.This solution ensures optimum energy management:b transfer to a replacement source according to external requirementsb management of power sourcesb regulationb emergency source replacement, etc.The automatic controller may be fitted with an option for communication with a supervisor.

Interlocking of a number of devices using keylocks (captive keys)Interlocking is based on two identical keylocks with a single key and a keylock adapter (different for each device). This solution enables interlocking between two devices that are physically distant or that have very different characteristics, for example between a low and a medium-voltage device, or between Compact NS circuit breakers and switch-disconnectors.A system of wall-mounted captive key boxes makes possible a large number of combinations between many devices.

Mechanical interlocking

Electrical interlocking of two or three devices is used to create a remote-operated source-changeover system. A basic mechanical interlocking system enhances the reliability of system operation.

Interlocking of two Compact NS100 to 630 devices using a base plateA base plate designed for two Compact circuit breakers can be installed horizontally or vertically on a mounting rail. Interlocking is carried out on the base plate by a mechanism located behind the breakers. Access to the circuit breaker controls and trip units is conserved. Circuit breakers must be fixed or plug-in versions, with or without earth-leakage protection or measurement modules. The base plate and the circuit breakers are supplied separately.b base plate for Compact NS100 to 250 devicesThis base plate is intended for two Compact NS100 to 250 devices.b base plate for Compact NS400 to 630 devicesThis base plate is intended for two Compact NS400 to 630 devices. It may also be used, without any modifications, to interlock a fixed Compact NS100 to 250 with a Compact NS400 or 630 device.An adapter kit is required for plug-in versions of the Compact NS100 to 250 devices.Compact NS100 to 250 devices, in both fixed and plug-in versions, may be equipped with spreaders.

Electrical interlocking

Electrical interlocking is used with the mechanical interlocking system. It electrically interlocks the two circuit breakers and implements the time delays required for proper operation of the system.An automatic controller may be added to take into account information from the distribution system.

Electrical interlocking is carried out by an electrical control device.For Compact NS up to 630 A, electrical interlocking is implemented by the IVE unit integrating control circuits and an external terminal block. The integrated control circuits implement the time delays required for correct source transfer.For Compact NS630b to 1600 and Masterpact, this function can be implemented in one of two ways:b using the IVE unitb by an electrician based on the diagrams presented in the “Electrical diagrams” part of this catalogue.

Characteristics of the IVE unitb external connection terminal block:v inputs: circuit breaker control signalsv outputs: status of the SDE contacts on the “Normal” and “Replacement” source circuit breakersb 2 connectors for the two “Normal” and “Replacement” source circuit breakers:v inputs:- status of the OF contacts on each circuit breaker (ON or OFF)- status of the SDE contacts on the “Normal” and “Replacement” source circuit breakersv outputs: power supply for operating mechanismsb control voltage:v 24 to 250 V DCv 48 to 415 V 50/60 Hz - 440 V 60 Hz.The IVE unit control voltage must be same as that of the circuit breaker operating mechanisms.

BA controller

The BA controller is used to create simple source-changeover systems that switch from one source to another depending on the presence of voltage UN on the “Normal” source.It is generally used to manage two permanent sources and can control Compact NS and Masterpact NT/NW circuit breakers and switch-disconnectors.

Operating modesA four-position switch may be used to select:b automatic operationb forced operation on the “Normal” sourceb forced operation on the “Replacement” sourceb stop (both “Normal” and “Replacement” sources off).

Setting the time delaysTime delays are set on the front of the controller.t1. delay between detection that the “Normal” source has failed and the transmission of the order to open the “Normal” source circuit breaker (adjustable from 0.1 to 30 seconds).t2. delay between detection that the “Normal” source has returned and the transmission of the order to open the “Replacement” source circuit breaker (adjustable from 0.1 to 240 seconds).

Circuit breaker commands and status indicationsThe status of the circuit breakers is indicated on the front of the controller.b ON, OFF, fault.A built-in terminal block may be used to connect the following input/output signals:b inputs:v voluntary order to transfer to source R (e.g. for special tariffs, etc.)v additional control contact (not part of the controller). Transfer to the “Replacement” source takes place only if the contact is closed (e.g. used to test the frequency of UR, etc.)b outputs:indication of operation in automatic or stop mode via changeover contacts.

TestIt is possible to test the operation of the BA controller by turning OFF (opening) the P25M circuit breaker for the “Normal” source and thus simulating a failure of voltage UN.

UA controller

The UA controller is used to create a source-changeover system integrating the following automatic functions:b transfer from one source to another depending on the presence of voltage UN on the “Normal” sourceb startup of an engine generator setb shedding and reconnection of non-priority circuitsb transfer to the “Replacement” source if one of the phases on the “Normal” source fails.The UA controller can control Compact NS and Masterpact NT/NW devices.

Operating modesA four-position switch may be used to select:b automatic operationb forced operation on the “Normal” sourceb forced operation on the “Replacement” sourceb stop (both “Normal” and “Replacement” sources off, then manual operation).

Setting the time delaysTime delays are set on the front of the controller.t1. delay between detection that the “Normal” source has failed and the transmission of the order to open the “Normal” source circuit breaker (adjustable from 0.1 to 30 seconds).t2. delay between detection that the “Normal” source has returned and the transmission of the order to open the “Replacement” source circuit breaker (adjustable from 0.1 to 240 seconds).t3. delay following opening of QN with load shedding and before closing of QR (adjustable from 0.5 to 30 seconds).t4. delay following opening of QR with load reconnection and before closing of QN (adjustable from 0.5 to 30 seconds).t5. delay for confirmation that UN is present before shutting down the engine generator set (adjustable from 60 to 600 seconds).t6. delay before startup of the engine generator set (120 or 180 seconds).

Commands and indicationsCircuit breaker status indications on the front of the controller:b ON, OFF, fault.A built-in terminal block may be used to connect the following input/output signals:b inputs:v voluntary order to transfer to source R (e.g. for special tariffs, etc.)v additional control contact (not part of the controller). Transfer to the “Replacement” source takes place only if the contact is closed (e.g. used to test the frequency of UR, etc.)b outputs:v control of an engine generator set (ON / OFF)v shedding of non-priority circuitsv indication of operation in automatic mode via changeover contacts.

Distribution-system settingsThree switches are used to:b select the type of “Normal” source, whether single-phase or three-phase (e.g. 240 V single-phase or 240 V three-phase)b select whether to remain (or not) on the “Normal” source if the “Replacement” source is not operational during operation on special tariffsb select the maximum permissible startup time for the engine generator set during operation on special tariffs (120 or 180 seconds).

TestA pushbutton on the front of the controller may be used to test transfer from the “Normal” source to the “Replacement” source, then the return to the “Normal” source. The test lasts approximately three minutes.

COM communications optionUsing the internal bus protocol, this option may be used to remote the following information:b circuit breaker status (ON, OFF, fault trip)b presence of the “Normal” and “Replacement” voltagesb presence of an order for forced operation (e.g. special tariffs)b settings and configuration informationb status of non-priority circuits (loads shed or not)b position of the switch (stop, auto, forced operation on the “Normal” source, forced operation on the “Replacement” source).

Communications option for Compact NS and Masterpact NT/NWThe COM communications option is compatible with all the source-changeover systems for Compact NS100 to 1600 and Masterpact NT/NW circuit breakers and switch-disconnectors.It can be used to remote status information. It may not be used to operate the circuit breakers (only possible locally on the front of the UA150 controller).Masterpact and Compact NS630b to 1600 circuit breakers and switch-disconnectors are compatible with the Modbus ECO COM option.Depending on the trip units or control units used, the COM option may also be used to analyse distribution-system parameters required for the operating and maintenance assistance.
