Abstract
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.
