Reliability TGM3L RCCB Industrial Residual Current Circuit Breaker
DZ47LE-63G residual current circuit breaker is suitable for the
circuit of AC50/60Hz, 400V rated voltage, 63A rated current. When
there is body electric shock or current of grid leakage is over the
specified value, the residual current circuit breaker will cut the
power in a very short time to protection the body and safety of
electric equipment. DZ47LE -63G is also has the protection function
of overload, short-circuit, over-voltage, and it also can switch
the electric apparatus and illumination circuit frequently. It is
quiet applicable for industrial and commercial lighting system.
