Abstract
A circuit breaker is provided with a hook operating to hold the breaker movable contacts open against the bias of charged mechanism springs. The hook is selectively actuated 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 display the existing breaker condition.
