A power panel of an electrical distribution system including a bus stack with a plurality of conductive bars spaced from one another and a plurality of insulators, an electrical accessory is coupled to the plurality of bus bars, and each insulator includes a main body and a safety feature that extends from the main body. The safety features from adjacent insulators extend towards one another to define a gap sized to prevent insertion of a foreign object therein. The gap is further sized to permit insertion there through of a conductive component to establish an electrical connection between multiple bus bars and the electrical accessory.

An apparatus includes a circuit breaker and mounting bracketry fastened to the rear side of the circuit breaker. The mounting bracketry includes first and second spacer portions extending rearward from a respective locations inside the width of the circuit breaker unit, first and second fixation portions extending outward from the first and second spacer portions, respectively, to respective positions outside the width of the circuit breaker, and first and second hook portions extending rearward from the first and second fixation portions, respectively. The circuit breaker may be mounted to an electrical enclosure with the first hook portion and the second hook portion engaging a mounting rail of the electrical enclosure.

A heat sink is described for cooling an electrical component. The heat sink has heat dissipating structures connected to a base. The base is attached to a connector which makes contact with a heat transfer contact of the electrical component. The electrical component may be a power supply bus which supplies electrical current to a series of circuit breakers.

A collapsible link device includes a side frame, a carrier, a main contact arm, a plurality of collapsible links, and a release mechanism. The carrier is pivotably coupled to the side frame. The main contact arm is pivotably coupled to the carrier and includes a first end including a first electrical contact. The plurality of collapsible links are pivotably coupled to the side frame and the carrier. The release mechanism is pivotably coupled to at least one of the collapsible links and the carrier. The plurality of collapsible links are movable between an uncollapsed position in which the first electrical contact contacts a second electrical contact and a collapsed position that results from the first electrical contact separating from the second electrical contact.

A circuit breaker, and method of assembling the circuit breaker, includes a circuit breaker housing defining an interior portion, and which includes a molded base and a separable cover. The molded base includes an interior surface and an exterior surface. The exterior surface of the molded base is operatively disposed outside of the interior portion of the circuit breaker housing, and the exterior surface of the base defines at least one current sensing unit receiving cavity configured to receive a current sensing unit therein. The molded base and separable cover are cooperatively disposed to surround the interior portion of the circuit breaker housing.

A circuit breaker crossbar assembly includes a crossbar having a first and second segment, the first and second segment each operatively coupled to a respective moveable contact arm assembly. Also included is a coupling segment disposed between the first and second segment, the crossbar and the coupling segment rotatable about an axis. Further included is at least one support assembly operatively coupled to the coupling segment. The support assembly includes a bushing coupled to the coupling segment and rotatable with the crossbar and the coupling segment. The support assembly also includes a support bracket configured for affixation to a stationary structure and disposed adjacent to the bushing, the bushing rotatable relative to the support bracket. The support assembly further includes a fixing bracket engaged with the support bracket and disposed adjacent to the bushing, the bushing rotatable relative to the fixing bracket.
