ZW32 series outdoor high voltage vacuum circuit breaker is 11kv to 40.5kv 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 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.
It can be equipped with intelligent controller to protect branch circuits, automatically clearing circuit failures, such as earth between phases, short circuit between phases and overcurrent, ensuring the electrical safety for users without failures.
Operating mechanism: spring mechanism (manual/ motor ) / permanent magnet
Disconnecting switch: disconnecting at one side or both sides ( if needed)
Optional: CT, zero CT, PT, surge arrester
Control and protection: inrush current controller
Bell type FTU (optional)
Box type FTU (optional)
Installation: pole mounted
Standard
IEC 60056
