DGB3-80ZL

DGB3-80ZL series functional metering Residual current Operated Circuit- breaker is mainly used in AC 50Hz with rated working voltage 230V and with rated current up to 80A. In case of personal electric shock or when the grid leakage current exceeds the specified value, the residual current action circuit breaker can work to quickly cut off the power supply within the very short time for protection of the safety of personnel and electrical equipment as infrequent conversion of the line under the overload, short-circuit, overvoltage and normal situations, especially suitable for industrial and business lighting power distribution system.
