摘要： A multipole circuit breaker includes an arcing chamber housing with a number of arcing chambers, corresponding to the number of poles, arranged next to each other. Each arcing chamber has a hinged contact bridge cooperating with a stationary contact arrangement. An interrupter shaft common to the poles of the multipole circuit breaker and including a number of shaft segments made of an insulating material, in each of which a contact bridge is arranged, is provided. The adjoining shaft segments are joined to each other by a respective coupling element, each coupling element including two tab-shaped parts joined to each other by a support shaft. Each tab-shaped part supports at least two first connecting pins on a side facing away from the support shaft and extending in an axial direction. The shaft segments each include recesses a side facing the coupling element, the recesses for receiving the connecting pins. A support, or bearing, for supporting the support shaft is provided in the arcing chamber housing in a transition area between adjacent arcing chambers.
摘要翻译： 多极断路器包括具有多个彼此相邻布置的多个电弧室的电弧室壳体，电弧室对应于极数。 每个电弧室具有与固定接触装置配合的铰接接触桥。 一种与多极断路器的极共同的断路器轴，包括由绝缘材料制成的多个轴段，每个轴段设置有接触桥。 相邻的轴段通过相应的联接元件彼此连接，每个联接元件包括通过支撑轴彼此连接的两个翼片状部分。 每个翼片形部分在远离支撑轴并在轴向方向上延伸的一侧支撑至少两个第一连接销。 轴段各自包括面向联接元件的一侧的凹部，用于接收连接销的凹部。 用于支撑支撑轴的支撑件或支承件设置在电弧室壳体中的相邻电弧室之间的过渡区域中。

摘要： A latching device for a circuit breaker includes a manual operating toggle moveably arranged between an OFF-position and an operation-readiness position, a moveable contact and a fixed contact, wherein the moveable contact is configured to open and close a main circuit of the circuit breaker. An energy storage mechanism is configured to store an actuating force of the toggle by the toggle being moved from the OFF-position to the operation-readiness position and to exert the stored force to the moveable contact to close the main circuit of the circuit breaker. A removable retention lever is configured to prevent movement of the moveable contact into a closing position upon the energy storage mechanism exerting the stored force to the moveable contact. A holding mechanism is configured to hold the toggle in the operation-readiness position.
