摘要： A circuit protection device for monitoring a current flowing from an electrical distribution line through a trip mechanism to a load includes an input conductor configured to receive a current signal from a sensor. At least one resistor is arranged to receive the current signal from the input conductor, and provides a voltage signal proportional to the current signal. The circuit protection device includes a control circuit coupled in parallel with the resistor and a power supply that receives the current signal from the resistor and supplies power to the control circuit based on the current signal. The control circuit is configured to receive the voltage signal and determine an amplitude of the current flowing through the trip mechanism based on the voltage signal. The control circuit is also configured to determine whether a predetermined current threshold is exceeded and to generate a control signal to activate the trip mechanism.
