What Is An Electronic Leakage Circuit Breaker?

Electronic leakage circuit breaker is mainly composed of zero-sequence current transformer, electronically controlled leakage release and circuit breaker with overload and short-circuit protection. When leakage occurs in the protected circuit or electric shock occurs to a person, as long as the leakage current reaches the designed action current value, the secondary winding of the zero-sequence current transformer will output a signal and actuate the circuit breaker through the leakage release, thereby cutting off the power supply and playing a role in leakage and electric shock protection.
