Summarize:

VS1-12 series indoor fixed high-voltage vacuum circuit breaker is an indoor switchgear with three-phase AC 50HZ and rated voltage 12KV. 

It can be used for the control and protection of industrial and mining enterprises, power plants and substations, 

and electrical facilities, and is suitable for Places with frequent operations. The operating mechanism is integrated with the circuit breaker body.

 The design can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form a special propulsion mechanism

 and be used as a handcart unit. The main circuit part can use integrally sealed poles to achieve miniaturization,

 high reliability and maintenance-free circuit breaker. It can be equipped with center-mounted handcart switch cabinets such as KYN28A-12 (GZS), 

and the fixed type can also be equipped with XGN Series of fixed switch cabinets.
