Product Description

VSM-12 Indoor 10kV 12kV Permanent Magnetic VCB fixed type Vacuum Circuit Breaker

Summary

The permanent magnet operating mechanism and the vacuum interrupter of the 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.
