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： 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.
摘要翻译：断路器的可动接触臂在打开位置被锁定，以防止由于受保护的电气系统中的短路而产生的非常高的磁力排斥力，反弹和可能的电弧再起弧。每个可动接触臂通过弹簧加载的凸轮机构安装在与主载架相连的辅助载架上，弹簧加载的凸轮机构允许可动接触臂在主载架通过弹簧驱动断路器操作机构转动到打开位置之前打开。在本发明的一个实施例中，可动接触臂通过凸轮机构的凸轮表面中的锁定定位器在打开位置锁定。在一个优选实施例中，第二承载体由由固定支撑件悬臂的板簧形成的制动器锁定。通过操作机构随后旋转主载架，通过使辅助托架旋转而脱离由弹簧形成的制动器的闩锁。
