ZW32-12/T630-20G Integrated Outdoor Vacuum Circuit Breaker
The ZW32-12/T630-20G is an integrated (fusion) outdoor AC high-voltage vacuum circuit breaker rated at 12kV. Deeply integrates the vacuum circuit breaker body, high-power capacitor power supply module, built-in isolation switch, and current sensors into one unit. The pillar-type three-phase structure features solid-sealed poles with patented solid insulation technology, solving partial discharge, interface gap, and inherent stress issues. Suitable for overhead distribution lines, industrial applications, and distribution automation (FA/DA).
