Home / Products / Vacuum circuit breaker / Metal-Enclosed Three-Position Vacuum Circuit Breaker
This product is an indoor metal-enclosed three-position high-voltage vacuum circuit breaker. The main circuit adopts an encapsulated-pole structure that integrates the vacuum interrupter with the insulating support, giving it high insulation reliability and a compact structure, suitable for switching control and protection in 3.6-12kV three-phase AC distribution systems.
Features:
The three-position structure enables reliable switching among the open, closed, and earthed states; combined with comprehensive mechanical and electrical interlocking devices, it effectively prevents mis-operation and safeguards operating safety; the mechanism operates stably with a long service life and good maintenance-free characteristics.
Applications:
Mainly used with metal-enclosed high-voltage switchgear, widely applied in substations, distribution rooms, and various industrial/mining enterprises' distribution systems, undertaking circuit and equipment switching control, fault protection, and earthing protection, meeting the requirements of frequent operation and repeated interruption of short-circuit current.
