Abstract:
A system for sensing and protecting against an overcurrent condition in an electrical circuitry, comprising:a processor configured to sense the overcurrent condition in an input signal of the electrical circuitry;an electromechanical interface unit coupled to the processor and configured to initiate an opening of the electrical circuitry via a low release current, in response to a trip signal from the processor;a switch coupled between the processor and the electromechanical interface unit, the switch configured to receive the trip signal from the processor to permit the low release current to be transmitted to the electromechanical interface unit;a first capacitor coupled in parallel to the switch and the electromechanical interface unit; anda second capacitor coupled to the switch, wherein the first and second capacitors are configured to provide the low release current after transmission of the trip signal from the processor.
