Abstract
An auto-monitoring circuit including a first input structured to receive a signal from a processor of a circuit interrupter, a second input structured to receive power from a circuit protected by the circuit interrupter, a first switch structured to remain closed while the signal is received at the first input and remains above a predetermined threshold level and to open when the signal ceases to be received at the first input or drops below the predetermined threshold level, a second switch structured to remain open while the first switch is closed and to close when the first switch opens, and an output electrically connected to a trip circuit of the circuit interrupter. Closing the second switch causes a trip signal to be output to the trip circuit that causes the trip circuit to trip open the separable contacts.
