Product Description

High quality safety vcb ZW32-12D/630-20 series pillar type outdoor high-voltage

12kv vacuum circuit breaker


ZW32-12 series outdoor pole-mounted vacuum circuit breaker is a kind of outdoor three-phase

AC power distribution equipment at 12kV and 50Hz, mainly used for closing the load current

and opening overcurrent and short circuit current in the power system. It can be used as a section

switch in the distribution line, branch line and ring main and as a incoming switch in rural grid,

industrial and mining enterprises, residential areas, construction sites, etc.
