Abstract: A movable contact assembly for an electrical switching apparatus is provided. The movable contact assembly includes a number of shunts, and, a carriage assembly including two sidewalls and a contact arm assembly. The carriage assembly sidewalls are disposed in a spaced relation. The contact arm assembly includes a plurality of contact arms, a number of isolation members, a number of movable contacts, and an axle. Each contact arm defines an opening. One movable contact is disposed on each contact arm. Each contact arm is rotatably coupled to the axle with the axle extending through the contact arm opening. Each isolation member is disposed adjacent at least one contact arm. Each isolation member is coupled to, and in electrical communication with the adjacent contact arm. The shunts are coupled to, and in electrical communication with, the isolation members. In this configuration, no shunt operatively engages a contact arm.

Abstract: An interface assembly is for a trip unit of an electrical switching apparatus including a housing, separable contacts, and an operating mechanism for opening and closing the separable contacts. The trip unit cooperates with the operating mechanism and includes an enclosure, a controller, and a cover member having a plurality of indicia. The interface assembly includes at least one adjustment knob assembly having a post member and a ring member, which includes a cutout. The post member has first and second opposing ends. The ring member is disposed on the second end. The adjustment knob assembly pivots among a plurality of positions to adjust the controller. Each position corresponds to a predetermined setting of the trip unit. The ring member substantially overlays all but one of the indicia, which is exposed by the cutout to indicate the adjustment knob assembly position and corresponding trip unit setting.
