Abstract
A manually operated mechanism of an industrial circuit breaker utilizes a hook to hold the movable contacts open against the bias of charged mechanism springs. Manual or closing solenoid initiated articulation of the hook releases the contacts for abrupt closure under the urgence of the discharging mechanism springs. An indicator appropriately positioned by the operating mechanism identifies the charged and discharged mechanism states.
