    摘要: A return spring mechanism is arranged to operate with a circuit breaker operating mechanism during a trip condition. The circuit breaker operating mechanism is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism is attached to the exterior of the circuit breaker frame and includes a return spring with a fixed end attached to the frame. When the circuit breaker is tripped, the return spring mechanism operates to provide an additional force to the handle yoke. The additional force applied by the return spring is predetermined to position the handle yoke intermediate to the handle yoke positions when the circuit breaker is off and on. Thus, the movement of the handle yoke to the intermediate position provides clear indication that the circuit breaker is in the tripped condition.

    摘要: A termination connector for a circuit breaker is disclosed. The termination connector preferably includes a plurality of single pole screw receiving members integrally attached by a molded housing for unitary attachment to a line or load end of a circuit breaker to assist in holding a nut or nut plate adjacent each screw hole in the circuit breaker's terminal straps. The molded housing preferably includes a line of perforations between each single pole screw receiving member so that the correct number of single pole screw receiving members can be retained and the others can be knocked off along the line of perforations. Provisions are disclosed for adaption of the connector to metric or English standard nut hardware. In addition, the termination connector and circuit breaker are provided with mating attachment devices for providing a simple yet secure connection.

    摘要: An auxiliary magnetic trip unit for a circuit breaker arranged on the load strap of an industrial-rated circuit breaker to interrupt circuit current upon occurrence of a high-level short circuit fault. The magnetic trip unit employs a magnet yoke, an armature, a trip lever for interacting with a latching mechanism of a circuit breaker operating mechanism, and a lever arranged to restrain the armature from moving toward the magnet yoke and to release the armature in response to a predetermined level of pressurized gas. Thus providing an auxiliary magnetic trip unit for use with circuit breakers for selective short circuit overcurrent protection in an electrical distribution system with circuit breakers connected in series.

    摘要: An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure. The spacers and protrusions serve to widen the stance of the operating mechanism for force distribution purposes, and also to minimize friction between movable components.

    摘要: A cassette assembly for rotary contact circuit breakers utilizing a first electrically insulative cassette half piece and a second electrically insulative cassette half piece which are arranged to mate with each other to form an enclosure. The electrically insulative cassette half pieces include improper installation rejection features for both the rotor and arc chute assemblies. The inner surface of a electrically insulative cassette half piece including a groove and recesses formed therein. A rotor is properly positioned within the electrically insulative cassette half piece by inserting a pin on the face of the rotor into the groove. An arc chute assembly is properly positioned within the electrically insulative cassette half piece by inserting a tab located on a side member of the arc chute assembly into a corresponding recess located in the electrically insulative cassette half piece.
