EVHA400
BESS components 400A DC contactor, DC 12-1500V, 12V/24V coil voltage.
High voltage DC contactor, normally open (SPST-NO), 400 amps rated load current, available with 12V/24V (PWM) coils. Rated voltage up to 1500V, it’s specially designed for high voltage DC switching application.
It’s widely used in EV, heavy truck, DC charging station solution, PCS, HVJB, BESS, energy storage system solution, industrial vehicle system solution, etc.
- Ceramic sealed.
- Magnetic arc blowout.
- Compact design, low noise.
- High performance, high reliable.
- CE, CCC and RoHS compliant.
EVHA Series DC contactors can switching DC load from 12VDC to 1500VDC,rated current from 40A to 1000A. Ideal for Avionics & Aerospace, Military, Heavy Trucks,DC charging station solution, industrial vehicle system solution,energy storage system solution,etc. These hermetically sealed contactors can be mounted in any position, can be used in nearly any harsh environment at temperatures from –40°C to 85°C. All EVHA Series contactors meet RoHS and CE,CCC Conformance requirements.
