摘要： A molded case circuit breaker has a moving conductor assembly which includes a modular carrier assembly incorporating a plurality of spring biased contact cam members each of which engages contact pressure lobes on a pair of contact arm laminations to provide contact pressure. In response to the magnetic repulsion forces generated by a short circuit, the springs compress allowing the cam members to pivot and side step the contact pressure lobes so that the contact arm blows-open with little resistance. The cam members and springs are preassembled in a transverse channel in the carrier body and laterally retained in place by side plates for easier pivotal attachment of the contact arm laminations to the lobes on the side plates. The side plate lobes raise the contact arm relative to the mass of the carrier to reduce eddy current heating and provide a positive off indication for welded contacts by restricting movement of lower toggle links of the operating mechanism which are coplanar with the side plates. A modular crossbar includes molded bearings engaged by or made integral with hexagonal metal shaft sections which extend into hex openings in the carrier bodies of adjacent poles.

摘要： A molded case circuit breaker has modular crossbar members which connect the contact arm carriers of a desired number of poles for opening and closing the separable contacts of all of the poles simultaneously by a single spring powered operating mechanism. The modular crossbar members comprise shaft sections which engage openings in the contact arm carriers of adjacent poles. Bearings support the shaft sections and mount the contact arm carriers for rotation about a common pivot axis. In a preferred embodiment of the invention, the modular crossbar member is a single continuous metal shaft overmolded with an electrically insulative resin which also forms the bearing. Alternatively, separate metal shaft sections seat in sockets on either side of the molded bearing. In both instances, the shaft sections are keyed to the openings in the contact arm carriers for transmission of torque. In the exemplary crossbars, the shaft sections are hexagonal in cross-section.

摘要： A securing member for use in a switch assembly of a circuit breaker includes a support post and a fastener. The securing member assists in mounting an alarm switch onto a bracket of the switch assembly and further resists movement of the actuation levers of a pair of auxiliary switches from moving beyond a first given position and from potentially becoming caught in an operating mechanism that pivots a crossbar. The dual functionality of the securing member is cost effective and occupies only a minimal amount of additional space within the crowded confines of the circuit breaker.

摘要： The movable contact arms of a circuit breaker are latched in the blow open position to prevent rebound and possible restrike of the arc in response to the very high magnetic repulsion forces generated by a short circuit in the protected electrical system. Each movable contact arm is mounted on a secondary carrier coupled to a main carrier by a spring loaded cam mechanism which allows the movable contact arm to blow open before the main carrier is rotated to the open position by the spring driven circuit breaker operating mechanism. In one embodiment of the invention, the movable contact arm is latched in the blow open position by a latching detent in the cam surface of the cam mechanism. In a preferred embodiment, the secondary carrier is latched by a detent formed by a leaf spring cantilevered from a fixed support. Subsequent rotation of the main carrier by the operating mechanism releases the latch by rotating the secondary carrier clear of the detent formed by the leaf spring.

摘要： A push-to-trip mechanism is provided for a handle assembly for an electrical switching apparatus, such as circuit breaker. The handle assembly includes a casing coupled to the exterior of the circuit breaker housing over the push-to-trip button of the circuit breaker. The push-to-trip mechanism includes an actuating member at least partially disposed within an aperture of the casing. The actuating member is movable between an actuated position corresponding to the actuating member actuating the push-to-trip button, and an unactuated position corresponding to the actuating member not actuating the push-to-trip button. A resilient element biases the actuating member toward the unactuated position. The push-to-trip mechanism is operable from the exterior of the handle assembly casing, thereby enabling the push-to-trip button of the circuit breaker to be actuated, without removing the casing.
