The Schneider Electric HVX 12‑25‑06/E 210 Vacuum Circuit Breaker is a medium‑voltage protective device designed for use in 12 kV AC power distribution systems. It employs vacuum interrupter technology to interrupt and make electrical circuits reliably under load and fault conditions with minimal contact wear, high dielectric strength, and fast arc extinction. The breaker is suitable for indoor switchgear applications and can be configured as a withdrawable (draw‑out) or fixed mounted unit within metal‑clad or metal‑enclosed switchgear. This type of breaker is commonly used to protect feeders, transformers, bus sections, and other critical assets in utility and industrial power distribution networks.
