The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker VSG-40.5C series vacuum circuit breaker is a new type of three-phase 50Hz according to the unique design concept and combined with the market demand and development, the rated voltage of indoor switchgear 40.5kV, it can be provided to industrial and mining enterprises, power plant and substation as the control and protection of electrical equipment, and is suitable for frequent operation.

The VSM-12 vacuum circuit breaker integrates a permanent magnet operating mechanism and a vacuum interrupter in a front-and-rear configuration. The breaker features a draw-out type design with a fixed arc-extinguishing column (solid sealing poles) and is designed for high reliability and performance in demanding electrical environments. The permanent magnet operating mechanism and the vacuum interrupter of the VSM-12M 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 an embedded pole Inside. The embedded pole 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.
