Abstract:

A programmable arc fault circuit interrupter (AFCI) is provided. The programmable AFCI includes a dual resistive shunt array for developing inputs to an analog front end which in turn develops trigger quantities for input to a programmable processor. The programmable processor determines if the trigger quantities, singularly, or in the aggregate, exceed predetermined thresholds. Determining the predetermined thresholds are exceeded the processor issues a trigger command to momentarily energize a delatching coil, thus removing AC mains power from a load.
