Abstract
A remote closing operator is positioned within a circuit breaker enclosure to allow remote operation of the circuit breaker operating mechanism to open and close the circuit breaker contacts. A pair of solenoids are employed to control the state of the contact closing springs. The first solenoid is energized to initially release the contact closing springs and the second solenoid is energized to interrupt the flow of current to the first solenoid.
