Rated 250 A continuous current at 200 V DC, with up to 2,000 A max cut-off capacity (at 80 V), delivering reliable high-current DC switching for EV and industrial power systems.
Engineered for high-cycle operation: 200,000 mechanical cycles and up to 50,000 make cycles on capacitive load (24 V DC), reducing maintenance and replacement costs.
Operates from -40°C to +85°C with 5%-95% RH humidity tolerance, suitable for harsh outdoor, vehicle-mounted and industrial environments.
Withstands 20 G sinusoidal vibration (80-2,000 Hz) and 20 G shock (1/2 sine, 11 ms), remaining stable in moving and high-vibration applications.
Silver alloy contacts with typical 1 mΩ initial contact resistance. Polarity-free design enables flexible, error-proof wiring in the field.
Quick and consistent actuation: close time max 30 ms (incl. bounce 5 ms), release time max 10 ms, for responsive system control and safety shutdown.
