41PR-3300 CIRCUIT BREAKER REMOTE CLOSE AND CHARGED SIGNALLING APPARATUS ABSTRACT A circuit breaker is provided with a hook operating to hold the breaker movable contacts open against the bias of charged mech- anism springs. The hook is selectively actuated by a closing solenoid to release the contacts for abrupt closure under the urgence of the mechanism springs. An indicator is appropriately positioned under the joint control of the breaker mechanism and movable contacts to identify OFF, charged and ON breaker conditions and to, in turn, control an actuating lever for a switch operating in an external charged signalling and closing solenoid circuit.
