ATS DescriptionCircuit breakers

ABB, Siemens or similar power interrupters IEC/EN 60947 AC1 listedOptional Tripping units will convert the interrupters into protection capable circuit breakers. This isa quite cost saving feature when the ATS is located close to the generator set. It performs thenthe generator protection and the switch function, avoiding double cost.

Steel Electrical panels and bus bar systems.Type-tested bus bar systemsThe type-tested bus bar systems consist of standard components and cover a range up to 8750

amps. The systems are tested by KEMA and ASTA according to IEC/EN 60439-1 to a short circuitlevel of 120 kA for 1 sec. and a peak withstand current of max. 264kA.

The bus bar sections are easily assembled in templates and fitted intothe panel. With specially developed assembly bolt, it is not necessaryto drill holes or cut threads. The assembly bolt allows for an adjustableconnection, exactly where it is needed on the bus bar holders. All busbar joints are designated as maintenance-free according toDIN 43671.

The bus bar systems are easy to install in the panel assembly.

Standard inserts are available for all kinds of circuit breakers/switcheson the market.Type-tested connections are ensured through the use of patented flexiblecopper conductors, which easily adapt to the various components makes. All inserts areconstructed with much built-in functionality for rational workshop installation and thus increasedcompetitiveness.

CATERPILLAR pays much attention to both personal safety and operational dependability andtherefore, selects good tested according to the market demand, such as earthquake test, shocktest and arcing test.

Type-tested steel panel systemsThe steel panels modular system is based on a concept of standardmodules for the construction of electrical panels. It is possible toconstruct an enclosure using a relatively few standard parts andcomponents.The versatility of the modular system makes it easy and quick toassemble and install electrical panels as well as to extend and/ormodify existing enclosures.These panels are all tested and/or type approved by several of theworlds most recognized test laboratories.

Furthermore, the panels are certified according to the norms in ISO9001.

OptionsThe IEC series ATS is offered with the below optional features.

Tripping unitThis option elegantly adds an electronic tripping device to one ofthe air circuit breakers.The tripping unit is the ABB electronic PR122 LSI type orequivalent.Using this option one can perform 50 and 51 ANSI protectionwith the ATS.One can add the protection to one or to both source sides of the ATS. If the unit is needed on bothsides, please add the option twice.Please select the appropriate option of 3 or 4 poles.Withdrawable breakerThis option converts a fixed circuit breaker in a withdrawable one. It adds a compatible drawer tothe cabinet.Using this option one can easily perform

service visits of the ATS Manual and visible lockout functions with the ATS.

One can add the protection to one or to both source sides of the ATS. If option is needed on bothsides, please add the option twice.Please select the appropriate option of 3 or 4 poles.

Power monitor Display

Displays kW, kVAr, Amps, Volts phase-phase, phase-neutral and more.Class 0.5s for measurement and metering according to IEC 62053-22.The power monitor provides effective solutions for network monitoring,installation sizing, energy management and electrical network qualitymeasurement.One can add the device on one or on both source sides of the ATS. If bothside is needed please add the option twice.

Relay logic.The relay logic is a classic relay type control of the ATS. It replaces the electronic controllerATS380.This option is useful in rare applications where electronic controller is not acceptable.

Generator Set Auxiliaries power feeders.Provides feeder protection for jacket water heater, space heater and battery charger. 230V or400V depending on configuration.

GOST certification.
