DZ47L leakage protection switch is suitable for AC 50/60Hz line with a rated voltage 230V for two-pole or a rated voltage 400V for four-pole and with a rated current up to 100A. When the electric shock occurs or the grid leakage current exceeds the specified value, the earth residual current circuit breaker can work to quickly cut off the fault current in a very short time to protect the safety of people and electrical equipment, and it can also be used for infrequent conversion of the line and for infrequent start of the motor. Products are suitable for many places such as industrial, commercial, high-rise and residential buildings.
