Self testing digital fault interrupter
First Claim
1. A fault interrupter apparatus having a line side and a load side and a conductive path there between, said apparatus comprising:
- a solenoid, adapted to move a plurality of contacts disposed in said conductive path from a first position to a second position;
an alarm indicator, adapted to provide status information on the operation of said fault interrupter apparatus; and
a processor, adapted to detect four condition states of said fault interrupter and indicate said four condition states of said fault interrupter using said alarm indicator.

Abstract
A fault interrupter apparatus having a line side and a load side and a conductive path there between. The apparatus includes a solenoid that is adapted to move a plurality of contacts disposed in the conductive path from a first position to a second position, an alarm indicator that is adapted to provide status information on the operation of the fault interrupter apparatus, and a processor that is adapted to detect four condition states of the fault interrupter and indicate the four condition states of the fault interrupter using the alarm indicator.

10. A fault interrupter apparatus having line terminals and load terminals and a conductive path there between, said apparatus comprising:
-
a fault sensing transformer, adapted to detect a fault condition in said conductive path;
a solenoid, adapted to move a plurality of contacts disposed in said conductive path from a first position when said solenoid is deenergized or to a second position when said solenoid is energized;
a switch, adapted to place said solenoid in said energized state in the absence of said fault condition and in said deenergized state in the presence of said fault condition; and
a varistor, adapted to protect said switch from transient voltage when said solenoid goes from said energized state to said deenergized state or said deenergized state to said energized state. - View Dependent Claims (11, 12, 13, 14, 15)
