VSG-12 indoor high-voltage vacuum circuit breaker

VSG-12 indoor high-voltage vacuum circuit breaker is an indoor and outdoor switching device used in 12KV power systems. It is used as a protection and control unit for power grid equipment and power design of industrial and mining enterprises. It is suitable for switching loads of different natures and frequent operations. The occasion of breaking short-circuit current for the first time. The product adopts VSG module integrated spring operating mechanism. The primary part of VSG-12 can use a sealed pole to seal the vacuum arc extinguisher and the main conductive circuit parts into a whole, protecting the arc extinguisher from collision, dust and condensation. It has strong environmental adaptability and greatly reduces the cost of the arc extinguisher. operation and maintenance costs.
