ZJQ250
EV parts 250A DC contactor, DC 12-450V, 12V-36V Coil
Lowest price DC contactor, normally open (SPST-NO), 250 amps rated load current, available with 12V-36V coils. It’s widely used in low speed EV, like Electric Forklift, Golf cart, etc.
- Epoxy sealed.
- Magnetic arc blowout.
- Coil voltage available 12-36V.
- Compact design, low noise.
- Bi-directional, optional with polarized or non-polarized contact.
- Optional Auxiliary contact.
- CE, CCC and RoHS compliant.
ZJQ Series DC contactors are designed as the cost effective low power contactors, rated voltage from 12VDC to 450VDC, range from 30A DC contactor to 350A contactors.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 low rapid vehicles like Electric Forklift trucks,Golf carts,power management systems for battery charging, fuel cells, battery backup where long life and high reliability are needed.All ZJQ Series contactors meet RoHS and CE Conformance requirements.
