Churod Americas, Inc. 400A High Voltage Direct Current Relay CHPV-S400

The CHPV-S400 is a 400A high voltage DC relay for energy storage and solar applications, using ceramic brazing and hydrogen gas to ensure arc containment and stable low contact resistance. It supports 1500VDC switching with a 2000A breaking current at 1000VDC, and carries a resistive load rating of 400A continuously at 85°C. The coil operates at 12VDC or 24VDC, consuming 55W or 6W respectively, with a 1-form A auxiliary contact rated at 6VDC/100mA. Insulation resistance exceeds 1000MΩ at 1000VDC; dielectric strength between coil and contacts is 4.0kVAC. The relay operates from -40°C to 85°C, weighs approximately 900g, and mounts via M6 screws with 6-8 N·m torque in horizontal or vertical orientation. Contact and coil terminations use screw terminals and connector, respectively.
