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.
