Abstract: A blocking member for an actuator having a movable arm for effecting a quick-make feature, includes, for example, an elongated member having a first end and a second end, wherein a portion of the elongated member is configured so that the blocking member disposed in a first position engages a portion of the movable arm of the actuator to restrain movement of the movable arm and so that the blocking member disposed in a second position disengages from the portion of the movable arm of the actuator to permit movement of the movable arm.

Abstract: A circuit breaker includes an electrically insulative case and a rotor assembly disposed within the electrically insulative case. The rotor assembly includes a contact arm and a rotor that is rotatable relative to the electrically insulative case. The contact arm is coupled to the rotor and movable between a first position in which a conductive path is closed and a second position in which the conductive path is open. The rotor assembly also includes a latch mechanism coupled to the rotor. The latch mechanism retains the contact arm in the second position during a short circuit event. The latch mechanism is spaced from the contact arm when the contact arm is in the first position. The latch mechanism engages the contact arm when the contact arm is in the second position.

Abstract: An interlocking system for a circuit breaker assembly including a circuit breaker having a plurality of contacts includes a racking screw coupled to the contacts that changes a position of the circuit breaker when engaged by a tool. The interlocking system also includes a front panel defining an opening through which the racking screw is accessible, an access door coupled to the front panel and configured to selectively cover the opening, and an access door stopper coupled to the front panel. The interlocking system also includes a trip assembly coupled to the access door stopper. Each of the access door, the access door stopper, and the trip assembly are moveable between a first position and a second position such that moving to the first position triggers delivery of a trip signal to the circuit breakers to open the plurality of contacts, and wherein, in the second position, the access door is fully open to enable access to the racking screw through the front panel.
