FL9 AC-S Type Earth Leakage Circuit Breaker(ELCB)

FL9 AC-S Type Earth Leakage Circuit Breaker(ELCB)

when people come across the electric shock or the leakage current of the electrical network exceeds the fixed value, When earth leakage circuit breaker tripping ,FL9 series products can cut off the fault current in short period so as to protect person and the equipments, It also can be used in the infrequent starting of the circuit and motors. FL9 Earth Leakage Circuit Breaker is suitable to industry, commerce, high-rise building, household and other kinds of places.
