VS1 Pro-12 Vacuum circuit breaker- with composite insulated pole

VS1 Pro Series indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear component with rated voltage of 12 kV and AC of 50 Hz. The products meet the requirements of GB / t1984-2014 high voltage AC circuit breaker, GB / t11022-2011 common technical requirements for high voltage switchgear and control equipment standards, JB / t3855-2008 high voltage AC vacuum circuit breaker, DL / t403-2000 technical conditions for ordering 12kV ~ 40.5kV high voltage vacuum circuit breaker.

The circuit breaker adopts modular spring operating mechanism with high mechanical stability. It can be stored by AC or DC power supply, or by hand. It has the advantages of small volume, strong breaking capacity, high insulation strength, no pollution, no explosion danger and so on. The product can provide control and protection for distribution facilities no matter under normal conditions or fault conditions (especially under short circuit conditions). Under rated parameters, the products can operate frequently and cut off short-circuit current for many times. The circuit breaker can be used not only for fixed installation unit, but also for special propulsion mechanism to form handcart unit.
