Patent ID: 7911746

Claim:
A fault circuit interrupting device comprising: a) a set of contacts to make and break a conductive path between line and load side conductors; b) a self test-circuit to test and reset the fault circuit interrupter and to transmit the results thereof to a remote device said circuit comprising: i) a microcontroller; ii) a communications circuit coupled to said microcontroller, said communications circuit disposed to communicate with a remote device the status of the fault circuit interrupter; c) a fault circuit having an input coupled to an output of said microcontroller, said fault circuit disposed to receive a disconnect signal from said microcontroller and for selectively opening said set of contacts to conduct a self test; d) a relay configured to open said contacts when power is removed comprising: i) at least one relay coil configured to open said contacts when power is removed from said coil; ii) at least one silicon controlled rectifier configured to selectively allow power to said at least one relay coil; iii) at least one transistor, in communication with said silicon controlled rectifier and with said microcontroller, said at least one transistor configured to selectively provide power to said silicon controlled rectifier to selectively actuate said silicon controlled rectifier to control said at least one relay coil to selectively open and close said contacts.
