ZW32-12/T Integrated Pole-Mounted Vacuum Circuit Breaker

Compact Outdoor VCB for 11–24kV Distribution Networks

The ZW32 integrated vacuum circuit breaker is engineered for outdoor overhead lines in 11kV to 24kV medium-voltage systems. Its pole-mounted design and integrated control box enable efficient switching, reclosing, and protection in remote or urban power distribution networks. Built for durability in harsh weather, ZW32 breakers are widely installed in rural substations, smart grids, and renewables.
