Pain Points in the Application Scenario

As the grid connection scale of photovoltaic arrays increases, the breaking capacity of 800V molded case systems reaches a bottleneck. The 800V AC system has protection blind spots in IT grounding fault protection.

Value of the Solution

The ultra-high breaking capacity design significantly enhances transformer system safety. It safely isolates grounding faults in 800V transformer IT grounding systems.
