The Schneider Electric HVX12‑25‑06/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 rapidly and safely interrupt electrical faults such as overloads and short circuits in three‑phase systems. This breaker is intended for indoor switchgear and offers reliable performance, long electrical and mechanical life, and compatibility with standard MV distribution switchgear. The “/E” indicates a withdrawable (draw‑out) configuration, and the 210 refers to the pole center distance (210 mm) suited to its frame and installation requirements. The HVX series supports various current ratings and short‑circuit capabilities for flexible system design.
