\nMCCB\u00a0Highlights
\n<\/h2>\n

1. Advanced and safe arc extinguishing system structure design;
\n2. Zero flashover can be achieved by installing the protective cover. Double insulation: pole to pole connection and complete isolation of main circuit;
\nThe 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 \u2192 AC1140V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.<\/p>\n
