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.

Vacuum interrupter
 Vacuum interrupter adopts the world's advanced manufacturing technology of miniaturized and high-performance interrupter;
 Contact is made of copper chromium alloy, with high vacuum degree;
 Cup style axial magnetic field (AMF) arc extinguishing, providing stable breaking performance;
 A single circuit breaker completes 274 times of rated short-circuit breaking E2;


Modular Mechanism
 Modular mechanism design, highly standardized structure;
 Mechanism is easy to assemble / disassemble and easy to maintain;
 High reliability with less number of parts
 Integrated charging handle, makes operation convenient and easy


Pot-type Pole
 Environment friendly insulating material, PA66 provides light weight, high dielectric performance;
 Recyclable and easy disposal after product life cycle;
 Cost effective and reliable;


Vacuum Circuit Breaker
 Fully meets the requirements of IEC and GB standards;
 Complete interlocking, prevent misoperation, and provide safety in operation;
 Modular design, shortened delivery time;
 Small opening rebound and excellent performance;
