Leakage protection switch
Current-type leakage protectors use a part of the zero-sequence current in the circuit (usually called residual current) as the action signal, and

The leakage protection switch of Small Power Distribution Board not only has the leakage protection function, but also is the main function of the leakage protector to ensure personal safety by tripping when people touch electrified power; If the electrical. The leakage protector is used to effectively protect the direct and indirect contact electricity of the low-voltage power grid. It provides overload and short-circuit protection, protecting lines or loads from overload and short. Many modern distribution boxes include a life-saving device called an Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD).
