Adjustable Current Earth Leakage Circuit Breaker

Earth leakage circuit breakers are used for protection against electrical leakage
in 50 / 60Hz circuits with rated single-phase voltage of 240V, or 3-phase voltage
of 415V, and rated current up to 60A.

When somebody gets an electric shock or the residual current of the circuit exceeds
the fixed value, the ELCB automatically cuts off power within the time of 0.1s
to protect personal safety and prevent equipment damage resulting from the residual
current.

Conforming with IEC standards, these breakers can protect circuits against switch
over under normal conditions.
