An electric shock prevention residual current circuit breaker provides electrical shock protection before contact of any current. The circuit breaker eliminating the flaws of the concurrent residual current circuit breakers comprises a digital logic microcontroller, a fault sensor circuit, an electromagnetic trip circuit, a low voltage supply circuit, a ground line circuit, and a set of corresponding members, such as a close or open circuit assembly, an input terminal, an output terminal, a switch handle, an overcurrent and short circuit trip device, a dynamic contact, a static contact, an avoiding arc device, a leakage detecting circuit, and a housing unit.
