A remote closing operator is positioned within a circuit breaker enclosure to allow remote operation of the circuit breaker operating mechanism to close the circuit breaker contacts. A closing solenoid and associated logic circuit controls the state of the contact closing springs. The solenoid is energized to initially release the contact closing springs and is later prevented from operation upon any further attempt to release the contact closing springs after the contacts are closed.

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.
