DGB3LE-40B

DGB3LE-40B series Residual current circuit breaker with overload protection is mainly used in AC 50Hz with rated working voltage 230V and with rated current up to 40A. In case of personal electric shock or when the grid leakage exceeds the specified value, the residual current circuit breaker can quickly cut off the power supply in a very short time for protection of the safety of people and electrical equipment and also for infrequent changeover of line and infrequent start of motor. This   product is suitable for various places such as industry, business, and high-rise residential buildings
