ABSTRACT:
An integrated circuit breaker is described having shunt trip capability along with automatic overcurrent protection. The shunt trip unit provides auxiliary power to the trip unit and allows the trip unit to report and record the shunt trip operation. A control circuit determines whether there is sufficient operating power available as well as the condition of the circuit breaker contacts prior to executing the shunt trip operation.
