VS1-12 Indoor high voltage vacuum circuit breaker/fixed

Overview

VS1-12 series indoor fixed high-voltage vacuum circuit breaker is an indoor switchgear with three-phase AC 50Hz and rated voltage of 12kV. It can be used for control and protection of industrial and mining enterprises, power plants, substations, and electrical facilities, and is suitable for Places with frequent operations. The operating mechanism is integrated with the circuit breaker body, and the design can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form a handcart unit. The main circuit part can use the integral solid-sealed pole to realize the miniaturization, high reliability and maintenance-free of the circuit breaker. It can be equipped with KYN28A-12 (GZS) and other mid-mounted handcart-type switch cabinets, and the fixed type can also be used with XGN Series fixed switchgear.
