Abstract: A contact assembly for an electrical device and a method for making such an assembly are presented. The contact assembly comprises a substrate and a contact material disposed on the substrate. The contact material comprises a composite material comprising a refractory material and a matrix material. The matrix material has a higher ductility than the refractory material. The composite material further comprises a core region and an outer region bounding the core region, the core region having a higher concentration of the refractory material than the outer region. The method applies cold spraying a blended feedstock to produce a layer that includes the composite material described above.

Abstract: 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.

Abstract: A mounting assembly for a circuit breaker mechanism includes a base and a mid-cover disposed adjacent the base. Also included is a first pair of mounting posts comprising a first mounting post and a second mounting post extending from the base, the first pair of mounting posts each protruding through the mid-cover. Further included is a first mount hole defined by the first mounting post and a second mount hole defined by the second mounting post. Yet further included is a first pin extending through the first mount hole, the second mount hole and a circuit breaker mechanism frame to retain the circuit breaker mechanism to the base.

Abstract: A circuit breaker crossbar assembly is provided and includes a crossbar rotatable between a first rotational position and a second rotational position, the crossbar is coupleable to at least one moveable contact arm of the circuit breaker. The circuit breaker crossbar assembly also includes an insert member disposed in communication with the crossbar and the at least one moveable contact arm to thereby exert a force on the at least one moveable contact arm.
