DZ47LE series miniature leakage circuit breaker is applicable to AC 50Hz or 60Hz lines
with rated voltage of 220V for the single-pole two-wire and two-pole, and 380V for the
three-pole, three-pole four-wire and four-wire, and rated current up to 63A. When personal
electric shock or power grid leakage current exceeds the specified value, the residual current
actuates the circuit breaker, which can quickly cut off the fault power supply in a very short time
and protect the safety of personal and electrical equipment. The residual current operated cir-
cuit breaker has overload and short circuit protection functions, which can be used to protect
the line or motor from overload and short circuit, and can also be used for infrequent switching
and starting of the line under normal conditions.
