ZN63(VS1)-24 Indoor Vacuum Circuit Breaker

Rated for three-phase AC 50Hz systems at 24 kV, the ZN63(VS1)-24 extends the ZN63 platform into the higher voltage class used for primary distribution substations, industrial main incomers, and utility ring-main applications across China, Southeast Asia, the Middle East, and Africa.

Breaking capacity runs up to 40 kA across a 630 A to 4000 A current range, with an E2-grade electrical endurance rating and a solid-sealed pole construction that keeps the main circuit maintenance-free through 25,000 mechanical operations.
