The ARM6HU features a pole-to-pole connection design that ensures complete isolation of the main circuit.

The products are widely utilized in the new energy sector, particularly in AC MCCB series inverter applications for power stations.

The PV string is inverted by the DC/AC inverter, after which the output AC is boosted and connected to the grid once converged by the AC combiner box.

They are designed to be equipped with AC circuit breakers operating at working voltages ranging from AC500V to AC800V.

For the direct grid connection mode, the operating voltage is relatively low, generally staying below AC400V.

The AC combiner box and the low-voltage side of the box substation require AC circuit breakers, with suitable working voltages operating from AC500V to AC800V.
