    Product Details

    MCCB Highlights

    1. Advanced and safe arc extinguishing system structure design;
    2. Zero flashover can be achieved by installing the protective cover. Double insulation: pole to pole connection and complete isolation of main circuit;
    The products are widely used in the field of new energy. AC MCCB: series inverter application (power station type): PV string is inverted by inverter DC/AC, and the output AC is boosted and connected to the grid after being converged by AC combiner box. AC combiner box and low-voltage side of box substation shall be equipped with AC circuit breaker, with working voltage of AC900V → AC1140V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.
