PRODUCT DETAILS:

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.

Ambient air temperature range: -5° C to 40 ° C, in addition, average temperature measured in 24 hours does not exceed 35° C.
Altitude <=1000m.
Daily average relative humidity should not exceed 95%. Daily average water vapor pressure should not exceed 2.2kpa;
Monthly average relative humidity should not exceed 90%. Monthly average vapor pressure should not exceed 1.8kPa.
Keep away from fire, explosion, serious pollution, chemical corrosion and violent vibration.
