Abstract
An apparatus and method for circuit interruption, with auto-power on and fault memory. The interrupter includes first and second locks in series with one another, and in series between the circuit driving source and load. The first lock is in communication with the circuit driving source. Control circuitry may be disposed between the circuit driving source and the first lock. When either lock is open the circuit is open; with both locks closed the circuit is closed. Actuating one lock does not change the state of the other lock. While closing input such as a power signal is applied to the first lock it is closed, and while the closing input is not applied it is open. When an opening input such as a fault signal is applied the second lock opens, and when a closing input such as a reset signal is applied the second lock closes.
