PowerPact H-, J-, and L-Frame Circuit Breakers

Trip Units

Mounting

The IFE interface and IFE interface + gateway are DIN rail mounting devices. A stacking accessory

enables the user to connect several IFMs (ULP to Modbus interfaces) to an IFE interface + gateway

without additional wiring.

24 Vdc Power Supply

The IFE interface and the IFE interface + gateway must always be supplied with 24 Vdc.

The IFMs stacked to an IFE interface + gateway have power supplied by the IFE interface + gateway,

thus it is not necessary to supply them separately. It is recommended to use a UL listed and

recognized limited voltage/limited current or a class 2 power supply with a 24 Vdc, 3 A maximum.

Required Circuit Breaker Communication Modules

The connection to an IFE interface or IFE interface + gateway requires a communication module

embedded into the circuit breaker:

•

PowerPact and Compact (fixed or drawout) circuit breakers: BSCM communication module

•

Drawout PowerPact and Compact circuit breakers: BSCM and its respective I/O (Input/Output)

application module.

All connection configurations for PowerPact and Compact circuit breakers require the circuit breaker

ULP cord. The insulated NSX cord is mandatory for system voltages greater than 480 Vac. When the

second ULP RJ45 connector is not used, it must be closed with a ULP terminator (TRV00880).
