Abstract:
1. A circuit interrupting device comprising: at least two conductive paths each having a line side and a load side; a fault sensor disposed to monitor the at least two conductive paths for a predefined fault condition and disposed to output a condition signal in the event the predefined fault condition is detected; a relay; a relay controller coupled to said relay and disposed to receive the outputted condition signal, such that when the relay controller receives the condition signal, said relay is disposed to cause electrical discontinuity in the at least two conductive paths between the line side and load side; a load voltage sensor disposed to measure the voltage between the at least two conductive paths at the load side and disposed to output a voltage signal in response to the measured voltage; and a power interrupting system having a power interrupting controller coupled to the fault sensor and the load voltage sensor and capable of outputting a disconnect signal in response to the detection of a predefined operational condition based upon the condition signal and the voltage signal, and a power interrupter disposed to cause permanent electrical discontinuity in the at least two conductive paths between the line side and load side in response to the disconnect signal.
