Electric leakage circuit breaker

The utility model discloses an electric leakage circuit breaker, and belongs to the field of low-voltage electric appliances. The technical problem that in the prior art, power cannot be timely switched on to restore power supply after regular automatic tripping trial is solved. The utility model provides an electric leakage circuit breaker, comprising a main processing unit used for generating anelectric leakage driving signal; the tripping unit is used for receiving the electric leakage driving signal to realize disconnection of the circuit breaker; the device comprises a sampling unit usedfor sampling current and voltage and outputting the current and the voltage to a main processing unit, and the main processing unit calculates and compares sampled values and performs electric leakage trial tripping after a judgment condition is met. According to the scheme, the technical problem that the residual-current circuit breaker cannot be switched on in time when the regular automatic tripping test is adopted is
