Describe Display

The CH3‑12KV/250 2500–3150A contact box is molded in one piece from epoxy resin, rated for 12 kV voltage and 2500–3150 A current. It withstands short‑time currents of 50 kA for 4 s and peak currents of 125 kA. Its IP67‑rated enclosure ensures complete dust and water protection, guaranteeing reliable long‑term performance in ambient temperatures from –40 ℃ to +40 ℃.

Compatible with a wide range of medium‑ and high‑voltage switchgear, this contact box is ideal for GIS, compact substations, wind/solar collector cabinets, and rail transit applications. Its compact design simplifies installation and maintenance, while the epoxy resin construction ensures outstanding mechanical strength and insulation. It is the perfect choice for systems demanding high‑current transmission, high reliability, and low maintenance costs.
