Abstract
An apparatus for facilitating interruption of current in an electrical circuit is provided and includes a current sensing device in the electrical circuit to service an electrical load, the current sensing device being productive of an output signal representative of a load current passing therethrough, a detection unit, in signal communication with the current sensing device such that the output signal is received by the detection unit, the detection unit being configured and disposed to output a secondary signal based on the output signal, and a microcontroller to receive and to decompose the secondary signal into detailed and approximate coefficients, and to generate a trip signal for use in interrupting an operation of the electrical circuit when a current of the sensed load is above a predetermined threshold and the detailed and approximate coefficients cooperatively indicate that threshold conditions for trip signal generation are satisfied.
