    • A microprocessor-based circuit breaker includes a chip that defines the current rating or ground fault current for the breaker. Thus, the maximum current rating and/or ground fault current can be set after manufacture using the chip that is electrically connected to the microprocessor. The breaker includes mechanical components that trip to disconnect the load terminal from the line input. The mechanical components include a floating breaker arm, trigger and tripper lever that cooperate to control the tripping of the breaker. A spring between the breaker arm and trigger, together with cam surfaces defined in the breaker switch cooperate to form a floating linkage to control the position of the breaker arm during on/off activation and current fault conditions. The circuit breaker also includes multiple indicia to provide a visual indication of the type of fault condition sensed by the breaker.
    • 基于微处理器的断路器包括限定断路器的额定电流或接地故障电流的芯片。 因此,可以在使用与微处理器电连接的芯片制造后,设定最大额定电流和/或接地故障电流。 断路器包括机械部件,其跳闸以将负载端子与线路输入断开。 机械部件包括一个浮动断路器臂,触发器和跳闸杆,用于控制断路器的跳闸。 断路器臂和触发器之间的弹簧以及限定在断路器开关中的凸轮表面协作以形成浮动联动装置,以在开/关激活和当前故障条件期间控制断路器臂的位置。 断路器还包括多个标记以提供由断路器感测到的故障状况的类型的可视指示。
