The 12V / 48V contactor is mainly used to control switching on/off of power supply of storage battery car, electric forklift, electric winch, electric car, excavator, air conditioner in vehicle.
Application
JX50DT/12V DC Contactor is designed and manufactured through precise calculation and rigorous testing to ensure that it can work properly in various harsh environments. In modern industrial systems, the role of high-voltage DC contactors can not be ignored.
