12kV Indoor Side-Mounted Vacuum Circuit Breaker

The VS1 indoor side-mounted vacuum circuit breaker, rated at 12kV, three-phase AC 50Hz, is specifically designed for use with fixed indoor high-voltage switchgear such as XGN. The product features a side-mounted spring-operated mechanism, an integrated frame structure, and a built-in vacuum interrupter, relying on a vacuum medium to extinguish the arc. Our products are available in various current and voltage options.

Product Details

Feature

  • High Adaptability:The side-mounted spring mechanism is specifically designed for fixed high-voltage switchgear such as XGN66 and XGN15.
  • Space Saving:Compared to traditional front-mounted designs, it occupies less space, providing ample internal wiring space.
  • High Mechanical Stability:The rigid base integrates the arc-extinguishing chamber, transmission components, and spring mechanism, resulting in a short transmission link, stable mechanical characteristics, and excellent synchronization between opening and closing.
  • Low Maintenance Costs and High Safety:Utilizing a mature vacuum arc-extinguishing chamber, it boasts strong breaking capacity, eliminates the risk of explosion, and confines the arc within the chamber, minimizing daily maintenance.
  • Wide Applicability of the Spring Mechanism:Spring-driven energy storage allows for frequent operation; compatible with both AC and DC, it features manual energy storage for manual opening and closing during power outages.
  • Long Mechanical Lifespan:The mechanical opening and closing operation can withstand tens of thousands of cycles.
  • Convenient Inspection and Maintenance:The exposed side mechanism facilitates fault diagnosis, easy component replacement, and efficient operation and maintenance.
