What terminations do I use to wire a shunt trip to a Masterpact NW circuit breaker for remote operation?

Issue:
Shunt trip wiring

Product Line:
Circuit Breakers

Environment:
Electrical Distribution Equipment

Cause:
Field wiring of shunt trip and shunt trip with communications.

Resolution:
The connector is MX1. For the standard shunt trip use C1 as the common and install a switch in series with C2 for the power.

For electrical operation of the communicating shunt trip use C1 as the common and install a switch in series with C2 for the power. Also, put maintained power on C3.

For modbus control of the communicating shunt trip use C1 as the common and supply maintained power on C3.  Plug the BCM harness into the shunt trip and operate with comms.
