摘要： A ground fault circuit interrupting device detects an end-of-life condition. A ground fault detecting circuit detects a fault condition and controllably operates a switching device to energize a circuit interrupting device. An end-of-life detecting circuit detects a failure of the circuit interrupting device to open after detection of the fault condition, and activates a secondary circuit to energize the circuit interrupting device.
摘要翻译： 接地故障电路中断装置检测到寿命终止状况。 接地故障检测电路检测故障状态，并可控制地操作开关装置以使电路中断装置通电。 寿命终止检测电路在检测到故障状态之后检测到电路中断装置的故障打开，并激活二次电路以使电路中断装置通电。
