ABSTRACT:
An input detecting circuit for an electric-leakage protection device with self-diagnostic function includes an analog electric-leakage unit, a magnetic electric-leakage induction ring, an operational amplifier, and an inverse feedback circuit. The inverse feedback circuit includes a first resistance and a second circuit unit shunted with the first resistance. The second circuit unit includes a second resistance and a unidirectional break-over unit connected in series with the second resistance.
