Abstract
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.
