Earth leakage circuit breaker circuit

The leakage detector circuit is suitable for circuits with 380V AC and below (50-60Hz), current 10-100A, and the neutral point of the power supply is grounded.
When a person gets an electric shock or the power grid leaks, it can quickly disconnect the faulty circuit and serve as leakage protection. It can also protect the line and motor from overload and short circuit
; it can also be used for infrequent switching of the line and infrequent starting of the motor.
    This leakage breaker is a current-operated type, mainly composed of a current zero-sequence transformer made of high magnetic permeability materials, an imported high-performance operational amplifier integrated block, an electric
release a J circuit breaker with zero-crossing and short-circuit protection. The components are housed in a plastic case. When there is leakage in the protected circuit or personal
electric shock, as long as the leakage or leakage current reaches the electric action current value, the secondary winding of the zero sequence current transformer will output a signal, and the circuit breaker will be at O. Is through
the leakage release . Cut off the power supply within a certain period of time to protect against leakage and electric shock.
