The leakage circuit breaker DZ47LE-63/1P is suitable for use in AC 50Hz or 60Hz circuits with a rated voltage not exceeding 400V and a rated current of 63A. When a person is electrocuted or the leakage current of the power grid exceeds the specified value, the leakage circuit breaker DZ47LE-63/1P can quickly cut off the faulty power supply in a very short time. Protect the safety of personnel and electrical equipment, while also protecting against overload or short circuit of circuits and motors. It can also provide protection against fires caused by grounding faults that persist due to the failure of overcurrent protection devices. The DZ47LE-63/1P (TX47LE) residual current circuit breaker can also be used for infrequent switching in the circuit and infrequent starting of the motor. The residual current circuit breaker DZ47LE-63/1P is suitable for various places such as industrial, commercial, high-rise buildings, and residential buildings.
