Abstract
A circuit interrupting device including one or more line terminals for connecting to an external power supply, one or more load terminals for connecting to an external load, an interrupting device, a fault detection circuit, and an auto-monitoring circuit. When the auto-monitoring circuit determines that the circuit interrupting device has reached its end-of-life, and it is determined that contacts of said interrupting device have not failed, then a signal is driven to a first level to actuate a switch and open the contacts. Additionally, said signal may further be driven to a second level to inhibit said circuit interrupting device from resetting when it is determined that contacts of said interrupting device have failed.
