CH3-12KV/180 Contact Box 1250A

The CH3‑12KV/180 1250A contact box is molded in one piece from high-strength epoxy resin, rated for 12 kV voltage and 1250 A current. It withstands short-time currents of 31.5 kA for 4 s and peak currents of 80 kA. With insulation levels of 42 kV (1 min power-frequency withstand) and 75 kV (lightning impulse withstand), it performs reliably in ambient temperatures from –40 ℃ to +40 ℃. The IP67-rated enclosure offers full dust and water protection, ensuring safe and dependable operation even in harsh outdoor environments.

The CH3‑12KV/180 1250A contact box is compatible with a wide range of medium- and high-voltage switchgear, making it ideal for GIS, compact substations, wind/solar collector cabinets, and rail transit projects. Its modular, compact design greatly simplifies field installation and maintenance. The epoxy resin construction not only enhances mechanical strength but also maintains outstanding insulation performance over the long term. This product meets the demanding requirements of modern power systems for high reliability, safety, and low maintenance, making it the perfect choice for insulation accessory solutions.
