ZN63A(VS1)-12 Indoor Permanent Magnet Vacuum Circuit Breaker

The ZN63A(VS1)-12 pairs the ZN63 vacuum interrupter platform with a permanent magnet operating mechanism, built for opening and closing electric loads in applications that call for frequent operation and a defined number of short-circuit breaking cycles.

Breaking capacity runs up to 40 kA across a 630 A to 4000 A current range, with a dual-stable-state permanent magnet mechanism that keeps the drive maintenance-free through at least 20,000 mechanical operations.
