    Product overview

    The VS1 series vacuum circuit breaker is independently developed by Knkong-electric and adopts a modular structure, which makes the VS1 vacuum circuit breaker easy to install, maintain, test and operate. Compared with traditional VS1 circuit breakers, Knkong-electric's VS1 is more stable, safer and has a longer service life. VS1 vacuum circuit breaker can meet the application requirements in 12kV and 24kV power transmission and distribution systems.
    It is widely used in electric power, energy, petrochemical, metallurgy, manufacturing, transportation, construction, environmental protection and other industries.

    VS1-Series circuit breaker features high stability and high reliability

    The operating mechanism of Knkong-electric's VS1 series vacuum circuit breaker is specially optimized for transmission components. The modular spring mechanism makes maintenance more convenient, the maintenance time after power failure is greatly shortened, and the parts are universal. At the same time, the vacuum interrupter has good compatibility and greatly improved performance.
