High-Performance Outdoor Protection

The ZW8-12 vacuum circuit breaker is a high-voltage, three-phase AC outdoor switchgear designed for reliable performance in power distribution grids. Operating at 12kV, it effectively manages load, overload, and short-circuit currents. Its common-box design utilizes high-strength SMC insulation materials to ensure robust phase-to-phase safety and a long, maintenance-free service life.
