EVQ400
400A contactor high current, DC 12-900V, 12V-36V coil
EVQ400
400A contactor high current, DC 12-900V, 12V-36V coil
High voltage DC contactor, normally open (SPST-NO), 400 amps rated load current, available with 12V-36V coils. It’s specially designed for high current DC switching application, offer high continuous current up to 400A.
It’s widely used as EV contactor in charging station, main contactor in EV, HEV, photovoltaic/ Solar system, energy storage, AGV, UPS, etc.
- Epoxy sealed.
- Magnetic arc blowout.
- Compact design, low noise.
- Build-in energy saving board
- Optional auxiliary contact.
- CE, CCC and RoHS compliant.
EVQ Series Contactors can switch DC loads at both low and high voltage from 12 to 900VDC. 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. They are the preferred contactor (sometimes called a relay ) for electric vehicles, hybrid vehicles,heavy trucks and equipment, busses, emergency vehicles, boats, LRT, mining, power management systems for battery charging, fuel cells, battery backup, photovoltaic, wind and wave power systems where long life and high reliability are needed.All EVQ Series contactors meet RoHS and CE,CCC Conformance requirements.
