Product Description

The CH3-12KV/150 630-1250A contact box is molded from high-strength epoxy resin, rated for 12 kV voltage and 630-1250 A current. It withstands short-time currents of 25 kA for 4 s and peak currents of 63 kA, with outstanding insulation levels of 42 kV (1 min power-frequency withstand) and 75 kV (lightning impulse withstand). With an IP67 protection rating and an ambient temperature range of -40 ºC to +40 ºC, it offers robust defense against moisture, dust, and corrosive agents, guaranteeing safe and reliable operation.
The CH3-12KV/150 contact box is compatible with medium- and high-voltage switchgear, ideal for GIS, compact substations, mining, and rail transit applications. Its modular design simplifies installation and maintenance, while the high-performance epoxy resin material enhances mechanical strength and maintains long-term insulation integrity. The IP67 rating ensures continuous, stable operation in outdoor and humid environments. This product is the perfect solution to meet the high reliability and safety requirements of modern power systems.
