Project Description

High voltage DC Contactor-EVH400


400A High Performance High Current DC Contactor, DC 12-1500V, contactor coil available with 12V/24V

High voltage DC contactor, normally open (SPST-NO), high current 400 amps rated load current, available with 12V/24V coils. Rated voltage up to 1500V, it’s specially designed for high voltage DC switching application.
It’s widely used as EV contactor, main contactor in charging station, EV, HEV, Avionics & Aerospace, Military, heavy truck, photovoltaic/ Solar system, energy storage, AGV, UPS, etc.

  • Ceramic sealed.
  • Magnetic arc blowout.
  • Compact design, low noise.
  • High performance, high reliable.
  • CE, CCC and RoHS compliant.

EVH Series DC contactors can switching DC load from 12VDC to 1500VDC,rated current from 40A to 400A. Ideal for Avionics & Aerospace, Military, Heavy Trucks,Heavy commercial vehicles, 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 EVH Series contactors meet RoHS and CE,CCC Conformance requirements.
