Overview 

ZW32-40.5G outdoor high-voltage vacuum circuit breaker adopts a uniquely designed integrated sealed pole and a highly reliable operating mechanism. The device is mainly used in medium-voltage overhead line power grids to separate and close load currents, overload currents, and short-circuit currents.

◆ Extremely high reliability

◆ Completely maintenance-free throughout the life cycle

◆ High mechanical and electrical life

◆ The whole machine is small in size, light in weight, and easy to install.
