    Tips: Main function of miniature circuit breaker

    The function of the miniature circuit breaker is to quickly cut off the power supply circuit when the human body gets an electric shock or the equipment leaks, so as to prevent the human body and the equipment from being harmed.

    The miniature circuit breaker was once called the leakage protection circuit breaker, which is a kind of switching device to prevent the human body from getting electric shock or leakage in the low-voltage circuit and causing fire and explosion accidents. When the detection element receives the signal, the leakage release disconnects the main contact of the main circuit, which plays a protective role. The protective action current of the detection element and the leakage release is 30~100mA, and the protection action time is 0.03~0.1s.
