Residual current circuit breaker, mainly applicable to AC 50Hz, rated voltage 400V, rated current up to 800A in the distribution network, used to provide indirect contact protection to people, can also be used to prevent fire hazards caused by equipment insulation damage, resulting in ground fault current, and can be used to distribute electrical energy and protect the line and power supply equipment overload and short circuit, but also as the line of infrequent conversion and motor Infrequent switching and motor starting. Conventional leakage protection module with residual current protection circuit breaker work power sampling for two-phase, this series of circuit breakers for three-phase, if the lack of a phase, circuit breaker leakage protection module can still work normally; rated residual action current and maximum disconnection time according to the actual situation on site adjustable; when the phase voltage is reduced to 50V, leakage protection module can still work normally



Description of button indications for earth leakage circuit breakers.

Leakage circuit breaker residual leakage current action value can be set 30mA, 50mA, 100mA, 200mA, 300mA, 500mA, 1000mA and so on, can also be set to limit the action time, respectively, non-delayed and time-delayed type, the optional time of 0.1s, 0.5s and 1s.
