摘要： A circuit breaker includes separable contacts, an operating mechanism structured to open and close the contacts, and a trip unit cooperating with the operating mechanism to trip open the contacts. The trip unit includes a sensor structured to sense current flowing through the contacts, a processor structured to output a trip signal responsive to the sensed current, and a trip actuator. The trip actuator includes a housing including a recess, a coil within the recess, the coil having an opening therethrough, a magnet within the recess, a thermoplastic bushing including a conduit therethrough, the thermoplastic bushing being coupled to the housing, and an armature disposable within the opening of the coil and slidably disposed within the conduit of the thermoplastic bushing. The magnet attracts the armature toward the housing. A spring biases the armature away from the housing, in order to cause the operating mechanism to trip open the contacts.
摘要翻译：断路器包括可分离触点，构造成打开和闭合触点的操作机构，以及与操作机构配合以跳开开关触点的触发单元。跳闸单元包括构造成感测流过触点的电流的传感器，构造成响应于感测到的电流输出跳闸信号的处理器和跳闸致动器。跳闸致动器包括壳体，其包括凹部，凹部内的线圈，具有穿过其中的开口的线圈，凹部内的磁体，包括穿过其中的导管的热塑性衬套，热塑性衬套联接到壳体，以及电枢一次性在线圈的开口内并且可滑动地设置在热塑性衬套的导管内。磁体将电枢吸引到壳体。弹簧将电枢偏离外壳，以使操作机构跳开触点。
