  Summary

  The permanent magnet operating mechanism and the vacuum interrupter of the HX03-12/M vacuum circuit breaker adopt front and rear arrangement,. The main conductive circuit is a floor-standing structure. The upper and lower outlet seats and the vacuum interrupter are installed in a tubular insulating cylinder. Inside. The insulating cylinder is made of epoxy resin by APG process.This structure can prevent dust accumulation on the surface of the vacuum arcing chamber and prevent it from being damaged by external factors. It can ensure that the product still has good insulation performance in the humid and hot environment and serious pollution.

  Permanent magnet vacuum circuit breaker for indoor installation, air insulation, used to open and close various of different type of power load,Applicable to the construction and renovation of power grids such as urban nets, rural nets, mines and railways, especially the products absorb advanced technology and technology at home and abroad, with intelligent, high reliability, long life, maintenance-free and other characteristics. No pollution to the surrounding environment when used and it’s a green product.
