Features:

 

SYML series circuit breakers with residual current protection (hereinafter referred to as circuit breakers) are mainly suitable for distribution networks with AC 50Hz, rated voltage 400V, and rated current up to 800A. They are used to provide indirect contact protection to people and can also be used to prevent Insulation damage, fire hazard caused by ground fault current, and can be used to distribute electrical energy and protect the circuit and overload and short circuit of power equipment. It can also be used for infrequent conversion of lines and infrequent start of motors.

 

The rated residual operating current I△n and the rated residual current maximum operating time can be adjusted on site according to the actual situation; when the phase voltage is reduced to 85V, the leakage protection module can still work normally; it has a leakage alarm output function.
