Description
S(D)L series Leakage circuit breakers are suitable for AC 50Hz, rated voltage up to 400V, rated insulation voltage 690V, rated current 16-800A. In addition to the function of overload, short-circuit and under-voltage protection, the products have electric shock and leakage protection function and can prevent the fire caused by the aging insulation equipment. Mainly used as motor and circuit overload, short-circuit protection motor protection.
