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 AC500V → AC800V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.
