摘要： 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.

摘要： 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.

摘要： 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.
