ZW6-12 outdoor AC high-voltage vacuum circuit breaker is a new dry type outdoor vacuum circuit breaker developed try Nature Science and Technology. It is mainly used in 3-phase AC 12 kV, 50Hz urban power distribution network and countryside electric power network as an outgoing line, sectional, interconnection and branch switch to open or close the load current, overload current and short circuit in the power distribution system.
Main features of this product:
zw6-12 outdoor AC high-voltage vacuum circuit breaker (circuit breaker for short in the following) is mainly used in three-phase AC 12 KV and 50 HZ power system. It is used to break and close load current, overload current and short-circuit current in the electric power system. It is used to protect and control the power distribution system in transformer substation, industrial and mining establishments, and also suitable for countryside power network and places with frequent operation, and especially suitable for the transformation of the power network of city and countryside.
