The VKJ series high voltage vacuum circuit breakers represent advanced switching technology for medium voltage power distribution systems. These breakers utilize vacuum interrupters that provide superior arc-extinguishing capability and long electrical life.
Our circuit breakers are designed for indoor installation in switchgear and controlgear assemblies. The compact design ensures space efficiency while maintaining high performance standards. The main contacts are sealed in vacuum interrupters, eliminating the need for maintenance of the arc-quenching medium.
The operating mechanism features spring energy storage with motor charging, providing reliable operation under various conditions. Both manual and electric operation options are available to meet different application requirements. The breaker can be configured as fixed type or withdrawable type according to installation needs.
Key advantages include high breaking capacity, long mechanical life (up to 30,000 operations), minimal maintenance requirements, and environmental friendliness (no SF6 gas). The products comply with international standards and can be customized to meet specific project requirements.
