Outdoor AC High Voltage Vacuum Circuit Breaker

Outdoor AC High Voltage Vacuum Circuit Breaker is a key piece of power equipment widely used in 12kV distribution networks. As highly reliable Integrated Circuit Breakers, they combine primary switching, sensing, control and protection functions in one compact structure. Designed as Pole Mounted Breakers, they are suitable for outdoor overhead lines, box-type substations and rural power grids. These Power Protection Devices deliver fast and accurate fault interruption, effectively preventing short circuits and overloads to ensure stable power supply.   Adopting advanced vacuum interrupter technology and solid-sealed insulation, these Durable Circuit Breakers feature strong breaking capacity, long mechanical life and excellent resistance to harsh outdoor environments including humidity, corrosion and extreme temperatures. With high insulation performance, reliable operation and low maintenance requirements, they ensure long-term stable performance under complex working conditions.   Th…
