Project Description

automotive contactor-ZJQ30


30A high power contactor, DC 12-450V, 12V/24V Coil

Lowest price DC contactor, normally open (SPST-NO), 30 amps rated load current, available with 12V or 24V coils. It’s widely used in low speed EV, like Electric Forklift, Golf cart, etc.

  • Epoxy sealed.
  • Magnetic arc blowout.
  • Compact design, low noise.
  • Bi-directional, optional with polarized or non-polarized 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.
