Abstract
A circuit recloser that limits current through a power line when a fault condition occurs. The recloser includes a circuit interrupter that is switchable between a closed state, in which current is permitted to flow through the power line, and an open state, in which the current is interrupted. The interrupter switches to its open state in response to a fault condition, such as a current surge. The recloser also has a movable member that is operatively coupled to the interrupter for resetting the interrupter to the closed state from the open state when the movable member is moved. The movable member is configured for being remotely movable to close the interrupter. Preferably the recloser includes an electric drive to remotely move the movable member from a remote station, and a projection extends from the movable member to enable manual movement thereof. The movable member includes a shaft which the electric drive rotates by turning a slotted hub coaxially about the shaft. When hub rotates, ends of slots in the hub contact a drive pin that extends radially from the shaft. The slots allow manual rotation of the shaft without damaging the electric drive. Microswitches sense the position of the hub during its rotation.
