Vacuum Circuit Breaker 12kv

Product description

VS1 -12 series indoor high voltage vacuum circuit breaker is equipped with Modular mechanism, which has a more stable integrated performance. This VCB is used for AC 12kV, 50Hz indoor high voltage switchgear, widely applicable to power stations, substations, and industrial and mining enterprises to control or protection power transmission and distribution systems, specially for the important high altitude breaking load and frequent operation place and reliable interlock function.

The circuit breaker is designed as a front-rear split charging structure, which both can be used as a fixed installation unit, and also be equipped with the chassis as used in the mounted, handcart unit.

Dimension and outline

Our VS1 series is suitable for 12~40.5kV high voltage switchgear. It has excellent mechanical and breaking performance and is mainly used in National Grid substations. We has independent research and development production lines, combined with independent research and development tooling, mechanical characteristic curve testing, loop resistance testing, and mechanical running-in before leaving the factory to ensure the parameter performance of each product. We also has the production capacity of permanent magnet operating mechanism circuit breakers.
