Brief description of the product:

A breaker which used vacuum as an arc extinction medium is called a vacuum circuit breaker. In this circuit breaker, the fixed and moving contact is enclosed in a permanently sealed vacuum interrupter. The arc is extinct as the contacts are separated in high vacuum. It is mainly used for medium voltage ranging from 11 KV to 33 KV.
Vacuum circuit breaker has a high insulating medium for arc extinction as compared to the other circuit breaker. The pressure inside the vacuum interrupter is approximately 10-4 torrent and at this pressure, very few molecules are present in the interrupter. The vacuum circuit breaker has mainly two phenomenal properties.


1. The contact part is a completely sealed structure, which will not reduce its performance due to the influence of moisture, dust, harmful gases, etc., and it works reliably with stable on-off performance.
2. Within the service life of the vacuum switch tube, the contact part does not need maintenance and inspection, generally up to about 20 years. Small maintenance workload and low maintenance cost.
3.With multiple reclosing function, it is suitable for the application requirements in distribution network.
