        Application

             HUM2DL series Residual Current Circuit Breaker with Over-current Protection is the first choice to cooperate with the National Smart Grid. Using the LCD in Chinese/English, with multiple functions and more intuitive characteristic. MCCB with high breaking Capacity HUM8 series circuit breaker, high breaking capacity, breaking time accurate, integrated distribution integrated protection, with small size, easy installation, fixed value adjustable action stalls, easy operation, can be adapted to all Users, all kinds of environment, set on demand. The product uses RS-485 communication port to realize the function of remote parameter adjustment, information query and fault parameters download .It integrates over-current protection, short circuit protection, voltage protection and leakage protection, especially suitable for comprehensive protection at all levels in power grid.

        It is suitable for low voltage power grid system with direct grounding of three-phase four-wire neutral point. It is used to provide indirect contact protection to the risk of personal electric shock. It also can provide the protections of ground or power equipment of earth fault, over current, short circuit, over voltage, under voltage and lack of phase.

        It accords with the standard of IEC 60947-2.
