Fixed indoor 12 kV breaker with mechanism-body integration and solid-sealed poles — up to 4000 A / 40 kA, 20,000 mechanical operations and 50 full-fault interruptions; mates with XGN fixed switchgear.
The VS1-12 indoor fixed HV vacuum breaker (three-phase 50 Hz, 12 kV) controls and protects electrical facilities in industry, power plants and substations, and suits frequent-operation duty. The operating mechanism is integrated with the breaker body as a fixed unit; the main circuit can adopt integral solid-sealed poles for miniaturisation, high reliability and maintenance-free service, mating with XGN-series fixed switchgear.
