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 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.
摘要翻译：模制外壳断路器具有移动导体组件，该移动导体组件包括结合有多个弹簧偏置接触凸轮构件的模块化载体组件，每个弹性偏置接触凸轮构件接合一对接触臂叠片上的接触压力凸起以提供接触压力。响应于由短路产生的磁排斥力，弹簧压缩允许凸轮构件枢转并且侧向接触压力凸起，使得接触臂以几小阻力打开。凸轮构件和弹簧预先组装在载体主体中的横向通道中，并通过侧板横向保持在适当位置，以便更容易地将接触臂叠片枢转附接到侧板上的凸角。侧板凸起相对于载体的质量使接触臂升高以减少涡流加热，并通过限制与侧板共面的操作机构的下肘节连杆的运动来为焊接接触提供正断开指示。模块化横梁包括由六边形金属轴部分接合或与六边形金属轴部分一体形成的模制轴承，其延伸到相邻极的载体主体中的六边形开口。

摘要： A wire form rail adapter for use in connecting an electrical component to a mounting rail includes a wire form spring clip that is formed to provide both a connection portion and a spring portion. The connection portion is configured to selectively engage the mounting rail and retain the rail against the rail adapter. The spring portion is configured to provide a biasing force that urges the wire form spring clip toward a position in which the connection portion engages the mounting rail.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. A trip mechanism is disposed in the housing and has an automatic trip assembly that generates a tripping operation. The automatic trip assembly includes an armature and a magnetic yoke having pivot supports. The armature includes a head portion having a first hook-like member and an oppositely facing second hook-like member. The first hook-like member has a first recess, and the second hook-like member has a second recess. The automatic trip assembly includes a pivot pin positioned on the pivot supports and extending through the first recess and the second recess to provide a rotatable disposition of the armature. The assembly also includes a biasing member applying a force to the armature in a direction to normally rotationally displace a bottom portion of the armature away from the magnetic yoke.
