12KV Vacuum Circuit Breakers (VS1)
VS1 series indoor high voltage AC vacuum circuit breakers are indoor switching equipment with rated voltage of 12kV. It can be used for the control and protection of electrical facilities in industry and mining, buildings and substations, as well as in places with frequent operation. The products have high reliability and stability.
The vacuum circuit breaker is equipped with low power consumption modular spring operating mechanism to meet the requirements of electric and manual operation. After the mechanism stored energy, the closing operation is completed after receiving the closing signal or pressing the closing button by hand; After the closing action is completed, after receiving the opening signal or press the opening button by hand to complete the opening operation.
