400a Vacuum Dc Contactor Bus Charger Dc Contactor Electric Car Dc Contactors

Product Description
bus charger 400A vacuum dc contactor-electric car DC contactors
Product description and show:
1. Application
1. Use on Power of industrial machinery/electric machine control/motor control,circuit isolation,Circuit protection and safety device etc;
2. Use on automobile distribution and back-up;
3. Used on power control;
4. Used on electric automobile charging pile;
5. Used for solar power generation equipment;
6. Other dc high voltage applications.
2. Product feature
1. Control High current high voltage circuit switch.
Coated with epoxy,inert gas in inside,Combined with magnetic blow-out,so the product can carry high current high voltage.
2. Compact structure,very low work noise
Because of the use of the arc - free gap structure, so that the shape can be very small;
Because of using the structure of the contact seal in the inert gas tank, it can ensure efficient and safe cutting even if the contact gap is small;
Noise is very low as well as switch the high large current .
3. Excellent security
The contact seal is sealed inside the capsule, and the electric arc can not leak, thus ensuring good safety of the product.
4. The contact reliability is very good and steady.
The contact unit is sealed in an inert gas, so contact resistance can remain stable regardless of the environment. At the same time, it also realizes the dustproof and water repellency of contact parts.
5. No special requirement for installation
The movable part is light weight, and the anti-force is large, the product is just a small affected by gravity, and the bottom is installed, there is no special requirement on the installation position.
6. Versatility
Standard USES include: battery switch and standby equipment, dc voltage power supply control, circuit safety protection, etc.
7. omply with EU RoHS directive (2002/95/EC)
