Description

      VS1 (ZN63A) -12(24)M series indoor high voltage vacuum circuit breaker is equipped with Modular mechanism, which has a more stable integrated performance. This VCB is used for AC 12kV, 50Hz indoor high voltage switchgear, widely applicable to power stations, substations, and industrial and mining enterprises to control or protection power transmission and distribution systems, specially for the important high altitude breaking load and frequent operation place and reliable interlock function.

      The VCB can be used for extremely frequent operation place, equipped with KYN28A-12 handcart type switch cabinet, and the fixed type VCB can also be used for XGN series switch cabinets. It conforms to National Standard GB1984-2003, and the related IEC standards.

      The circuit breaker is designed as a front-rear split charging structure, which both can be used as a fixed installation unit, and also be equipped with the chassis as used in the mounted, handcart unit.
