What is the power requirement for the Modbus BCM used with Micrologic A, P, and H trip units for the PowerPacT P and R frame breakers?

Issue:
BCM Power Requirements with Micrologic Trip Units

Product Line:
Molded Case Circuit Breakers and Air Circuit Breakers

Resolution:
The BCM has a power requirement of 30 mA at 24 VDC. The power supply for the circuit breaker communications module must be separate and isolated from the power supply for the trip unit to avoid issues between the trip unit and the BCM.
