CURRENT FAULT DETECTOR AND CIRCUIT INTERRUPTER AND PACKAGING THEREOF

PROBLEM TO BE SOLVED: To provide a device and method for monitoring a current condition within a current path between the line side and the load side of an electrical circuit, and intercepting the current path when detecting a current fault condition.SOLUTION: A power supply electrically connected to the current path provides a control supply. A sensor system receives power from the power supply, monitors the current in the current path and outputs a sensor signal indicative of the current condition within the current path. A logic controller also receives power from the power supply, receives the sensor signal and removes the control supply from the power controller when the sensor signal does not satisfy an established criteria. The sensor system may include one or both of an imbalance sensor for monitoring the current balance among two or more electrical wires and over current sensors for monitoring a current in individual lines.
