CH/CHJ 12kV Contact Boxes

The CH series 12kV epoxy resin contact boxes are precision-molded insulation components designed for medium-voltage switchgear systems. With rated currents ranging from 630A to 4000A, and high withstand levels of 42kV/1min power frequency and 75kV lightning impulse, these components ensure safe and reliable current transmission.

Engineered for versatility, the series includes standard, reverse-mounted, and T-type configurations to adapt to a variety of electrical cabinet structures. The use of high-performance epoxy resin provides excellent thermal endurance, mechanical strength, and insulation integrity, making them ideal for harsh environments and high-fault-level installations.
