VK12-12P Vacuum circuit breaker with fixed pole

VK12-12P series indoor medium voltage vacuum circuit breaker is an indoor switch device component with rated voltage of 12KV and below, three-phase AC 50Hz. The circuit breaker is used with KYN28A -12 type switchgear, and can also be installed in fixed type such as XGN2.
Product Information


Product introduction of VK12-12P solid-sealed pole type indoor medium voltage vacuum circuit breaker
 VK12-12P series indoor medium voltage vacuum circuit breaker is an indoor switch device component with rated voltage of 12KV and below, three-phase AC 50Hz. The circuit breaker is used with KYN28A -12 type switchgear, and can also be installed in fixed type such as XGN2. Inside the switch cabinet. The circuit breaker adopts a spring operating mechanism and a circuit breaker body to be integrally designed, which can be used for a fixed installation unit or a special propulsion mechanism to form a hand truck unit.
Product information of VK12-12P solid-sealed pole type indoor medium voltage vacuum circuit breaker  
1. Solid-sealed pole structure
 The high-performance epoxy resin material is used to seal the vacuum interrupter and the upper and lower outlets together by the automatic pressure gel process (AGP), so that the vacuum interrupter is protected from dust, moisture and dirt, and at the same time, it is reduced. The adjustment of the circuit breaker improves the assembly quality and mechanical reliability.
2, unique design 
Professionally designing circuit breakers, featuring the VK12 series circuit breakers of our company.(Patent No. : ZL 2019 3 0002790.0)
3, high corrosion resistance  
The surface treatment of most parts in the product organization adopts advanced nickel-phosphorus alloy treatment process to ensure the product's high anti-pollution and anti-corrosion ability.(This data comes from the inspection (experiment) report of National Electric Product Quality Supervision and Inspection Center (No: 19K2235-S).)
4, long life 
The mechanical life of products with breaking currents of 31.5KA and below is up to 30,000 times; the mechanical life of products with breaking currents of 40KA is up to 20,000 times.(This data comes from the inspection (experiment) report of National Electric Product Quality Supervision and Inspection Center (No: 19K2235-S).)
5, highly reliable secondary system  
The electrical components are imported or the best in the country, which improves the stability and reliability of the secondary system.
6, one conductive circuit maintenance-free
7, high insulation strength 
 When used at an altitude of 2000 meters and below, it is necessary to replace any parts to meet the insulation requirements: the insulation parts are imported or the best domestic raw materials, while increasing the design margin and improving the insulation performance of the circuit breaker.
