Churod Americas, Inc. 40A High Voltage Direct Current Relay CHPV -S40

The CHPV-S40 is a 40A high voltage DC relay designed for energy storage, solar inverters, and charging systems, featuring a ceramic brazing seal and hydrogen-filled contacts to minimize oxidation and arcing. It is rated for continuous operation at 40A up to 85°C, with a maximum switching voltage of 1500VDC and breaking capacity of 60kW. The relay has a 1 Form A contact arrangement, screw terminal load connections, and wire coil termination. It measures 140g in weight and supports mounting in horizontal or vertical orientations via M4 screws with a torque of 2-3 N·m. Insulation resistance exceeds 1000MΩ at 1000VDC, and dielectric strength is 4.0kV between coil and contacts, compliant with IEC 60664-1. Electrical endurance includes 75,000 make operations at 750VDC/40A and 6000 cycles at 1500VDC/15A, with mechanical endurance of 200,000 operations.
