摘要： A circuit interrupting device having an auto-monitoring circuit for periodically testing various functions and structures of the device. The auto-monitoring circuit initiates an auto-monitoring routine which, among other things, generates a self-test fault condition and determines whether the detection mechanisms within the device properly detect the self-test fault. A test fault circuit is configured to generate one or more test pulses that cause the self-test fault condition and the test pulses are generated to occur outside of an active region of the fault detection circuit.

摘要： A circuit interrupting device that includes a line conductor, a load conductor, an interrupting device, a delay circuit, and a fault detection circuit. The interrupting device disconnects the line conductor from the load conductor when the circuit interrupting device is in a tripped condition. The delay circuit includes a first switch, a second switch, and a third switch, and delays the disconnecting of the line conductor from the load conductor. The fault detection circuit detects a fault condition and generates a fault detection signal when the fault condition is detected. The fault detection circuit provides the fault detection signal to the first switch to trigger the first switch, and the delay circuit delays the triggering of the second switch and the third switch. After an amount of time has elapsed, the second switch and the third switch are triggered to place the circuit interrupting device in the tripped condition.

摘要： An apparatus includes an interruption circuit in a power delivery path, and a fault detection circuit configured to provide a fault signal to selectively cause the interruption circuit to interrupt power delivery, wherein the fault detection circuit includes a fault detection integrated circuit (IC) and a sensing coil configured to sense a differential current between a phase conductive path and a neutral conductive path in the power delivery path. A processor is configured to selectively control a fault simulation circuit to simulate a fault in the power delivery path, detect a response of the fault detection circuit to the simulated fault, and determine if the response of the fault detection circuit is an expected response. The processor provides an override signal to the interruption circuit to prevent the interruption circuit from receiving a fault signal from the fault detection circuit during, and for a predetermined time after, the simulated fault.
