VS1 Spring operated mechanismDetailed product description：

Overview
The VS1-12 (ZN63A) series vacuum circuit breaker is an indoor high difficulty voltage switch with a rated voltage of 12kv for three-phase AC 50Hz. It is a product manufactured with technology introduced from Xi'an Senyuan Company. The product can be used for the protection and control of electrical facilities in industrial and mining enterprises, power plants, and substations. Our institution is equipped with VS1-12 vacuum circuit breakers.
