Abstract: A spring cap for an electrical switching apparatus having a housing, a stationary contact, a movable contact disposed on a moving arm, and a crossbar assembly. The crossbar assembly includes a crossbar, a first contact spring, a second contact spring, and a spring clip. The moving arm is coupled to the crossbar. The spring cap includes a first segment structured disposed between the spring clip and the first contact spring, a second segment disposed between the spring clip and the second contact spring, and a connecting portion connecting the first segment to the second segment. The spring clip is disposed between the moving arm and the contact springs. The spring cap supports the spring clip and evenly distribute bias forces of the contact springs.

Abstract: A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.

Abstract: An adjustable trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts and an operating mechanism for opening and closing the separable contacts. The adjustable trip assembly includes a load conductor, a magnetic assembly comprising a magnetic member and an armature movably coupled to the magnetic member, and a calibration assembly comprising a calibration bracket cooperating with the armature, and an adjustment mechanism being adjustable to move the calibration bracket and thereby adjust the position of the armature with respect to the magnetic member to calibrate the magnetic assembly. The magnetic assembly further includes a biasing element that biases the armature away from the magnetic member.

Abstract: Electrical switching apparatus and strain relief assemblies therefor are described herein. In one exemplary, non-limiting embodiment, a strain relief assembly includes a cover and a base, each of which include a number of grooves structured to receive a number of wires. Each groove has a first side and a second side, where the second side is located opposite the first side. Furthermore, located on the first side and/or the second side are a number of protrusions. The grooves and the protrusions serve to secure the number of wires within the strain relief assembly such that, if a force is applied to an end of the wire, the protrusions work to retain the wires with the assembly.

Abstract: An operating handle interface assembly is for an electrical system. The electrical system includes an enclosure having an interior and an exterior, and a plurality of electrical switching apparatus disposed within the interior. Each of the electrical switching apparatus includes an operating handle. The operating handle interface assembly includes a linking assembly structured to interconnect the operating handles of a plurality of the electrical switching apparatus. An elongated shaft includes opposing first and second ends. The first end cooperates with one of the operating handles of one of the electrical switching apparatus. The second end is disposed on the exterior of the enclosure. A handle attachment is coupled to the second end of the elongated shaft on the exterior of the enclosure. The handle attachment is operable among a plurality of positions to correspondingly operate the operating handles of all of the interconnected electrical switching apparatus.
