The VS1-12M series indoor high voltage vacuum circuit breaker (VCB) features a modular mechanism and draw-out type design. With a polar distance of 210mm (suitable for 800mm cabinet widths), it is rated for 12kV three-phase AC 50Hz indoor high-voltage switchgear. It is widely applicable to power stations, substations, and industrial mining enterprises for controlling or protecting transmission and distribution systems.
This product is specially designed for important high-altitude breaking loads and frequent operation environments. The operating mechanism utilizes spring energy storage, compatible with both AC/DC and manual operations. It can also be equipped with a long-life permanent magnetic actuator. The design conforms to National Standard GB1984-2003 and related IEC standards.
Equipped with an auto-regulated heating element, this vacuum circuit breaker maintains optimal internal temperature to eliminate moisture-related failures in coastal or high-humidity industrial applications.
Features an intelligent heating system that prevents condensation in humid environments, ensuring reliable performance from -40°C to +40°C for year-round protection.
