Technical advantages and characteristics of DC contactor:

1. Simple structure, high efficiency, light weight and convenient installation.

2. Arc suppression cover adopts composite structure with arc resistant plastic cover shell, which has good arcing and extinguishing performance, light ablation of contact, fast arcing speed, small arc spacing, arc cover is not easily damaged and easy to load and unload during maintenance;

3. DC contactors are designed into the main contact and arc contact composite structure. Arcing Angle parallel, arc extinguishing performance is good; DC contactor contact resistance is too large cause and solution.

4. Attractive coil reuse the best plastic packaging technology in the world at this stage, with excellent insulating layer compressive strength and impact toughness, not easy to be locked. For some models of the specifications of the DC contactor is also connected with the power adapter of the electronic device and the packaging coil. In actual operation, the electromagnetic induction adsorption force is high, the coil is too low, the temperature is low and the external interference signal is small.

5. Excellent flame retardant grade;

6. Adjustable anti-vibration ability.

Single-stage DC contactor is suitable for 50A-400A DC rated working current 50A-400A, working frequency 48V power supply circuit, suitable for programmed power supply or UPS power system software, conduction of the main power circuit. It is used for the starting and stopping of pure electric vehicles, bottled electric vehicles, battery forklifts, traction live locomotives, communication power supply and other industries.
