The Schneider Electric HVX12‑31‑12/K (HVX EP Series) Vacuum Circuit Breaker is a medium‑voltage circuit protection device designed for use in 12 kV AC power distribution networks. It uses vacuum interrupter technology to switch and interrupt fault currents in three‑phase systems with high reliability and minimal contact wear. This breaker is suitable for indoor switchgear applications and industrial or utility networks, offering draw‑out or fixed configurations, robust insulation, and strong breaking capability. It is engineered to help protect distribution lines, transformers, generators, and other critical electrical equipment from overloads and short circuits through rapid interruption of fault currents.
