Connecting MasterPacT NT/NW and PowerPacT P- and R-frame Circuit Breakers to the ULP System

Introduction

Use the circuit breaker BCM ULP cord to connect MasterPacT NT/NW and PowerPacT P- and R-frame circuit breakers to the ULP system. The circuit breaker must have a BCM ULP circuit breaker communication module.

BCM ULP Circuit Breaker Communication Module

Supplied with the circuit breaker, the BCM ULP circuit breaker communication module is installed behind the MicroLogic trip unit and is wired to the microswitches:

• For manually-operated devices:

  • OF, SDE and/or SD contacts

• For electrically-operated devices:

  • OF, SDE, PF, CH contacts

  • Connection kit to the MX1 and XF communicating voltage releases

The BCM ULP circuit breaker communication module is independent of the trip unit. It communicates two-way with:

• the ULP system via the circuit breaker BCM ULP cord

• the MicroLogic trip unit via an infra-red link

The BCM ULP part number depends on the circuit breaker type.

Circuit Breaker BCM ULP Cord

The circuit breaker BCM ULP cord is used to connect a MasterPacT NT/NW or PowerPacT P- and R-frame circuit breaker equipped with the BCM ULP module and/or a MicroLogic trip unit to a ULP module.

It is available in three lengths and terminates with a plug RJ45 connector for direct connection to a ULP module.
