Product Description
The main function:
1. Vacuum arc extinguishing, strong breaking capacity, long electrical life and 10,000 mechanical life;
2. Simple structure, maintenance-free, long maintenance period;
3. Good insulation performance and strong anti-pollution ability;
4. It can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazard;
5. Built-in current transformer, the lecturer's precision reaches 0.2, which can realize three-phase interactive protection;
6. With condensation controller, it can keep the circuit breaker running reliably under certain temperature and humidity.
