Churod Americas, Inc. 250A High Voltage Direct Current Relay CHEV-H250E

CHEV-H250E is a 250A high voltage DC relay designed for use in energy storage systems, construction machinery, charging piles, and solar inverters. It features ceramic brazing sealed technology with hydrogen gas filling to reduce contact oxidation and maintain low, stable contact resistance. The relay has a 1 Form A main contact arrangement rated for 1000VDC and 250A continuous current at 85°C, with a maximum switching power of 250kW and a breaking current of 2000A at 1000VDC. Insulation resistance exceeds 1000MΩ at 1000VDC, and dielectric strength between coil and contacts is 4.0kV AC. The coil operates at 12VDC or 24VDC with a nominal power of 6W. It meets IEC 60664-1 standards. Mounting is via M5 screws with 3N·m to 5N·m torque, and the relay weighs approximately 450g. The coil and terminals have no polarity. The package dimensions are not explicitly toleranced but fall under general tolerance specifications.
