Product Description

Product Description

ZW32-24 series outdoor high voltage vacuum circuit breaker is 12kv three phase AC 50/60Hz outdoor power distribution equipment. It is suitable for power distribution system protection and control in transformer substation and mining & industrial enterprises, as well as rural power grid with frequent operation. It can also be used as ring network power supply unit and terminal equipment. 
ZW32-24 vacuum circuit breaker can be combined with disconnector to be used as section switch. It is mainly used to break and make load current, overload current and short circuit current. 

standard:
IEC 60056

Features

 

1. Vacuum circuit breaker is three phase post type structure, reliable and stable breaking capacity, without combustion and explosion danger, maintenance free, small size, light weight, long service life
2. Vacuum circuit breaker is completely sealed, excellent sealing, damp-proof and anti-condensation performance, especially suitable for severe cold and humid places
3. Three phase pole and CT uses epoxy resin solid insulation, or epoxy resin coated with silicone rubber solid insulation, which is anti-high & low temperature, ultraviolet resistant and aging resistant. 
4. Operation mechanism is small size spring mechanism, reliable action, long mechanical life, up to 10000 operations.
