ZW32-12 outdoor vacuum cicuit breaker (hereinafter referred to as circuit breaker) is
an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC
50Hz.Mainly used for breaking and closing the load curent,overload curent and
short circuit curent in the power system.It is suitable for protection and control
in substations and industrial and mining enterprise power distribution systems,
and places where rural power grids are frequently operated.
The circuit breaker has the characteristics of smallsize,light weight,anti-condensation,
maintenance-free,etc.,and can adapt to harsh weather conditions and dirty
environments.
