              VED-12 vacuum circuit breaker.jpg

              VED-12 series indoor high voltage vacuum circuit breaker is suitable for 12kV air-insulated indoor

              switchgear, used as protection and control unit of power equipment of industrial & mining enterprise. Due

              to the super excellence, it is especially suitable for locations where requires the frequent operation under

              rated working current or multiple breaking under short circuit breaking current. The circuit breaker adopts

              the integrated design of operating mechanism and circuit breaker body, servers as not only fixed

              installation, but also draw-out type equipped with a special propelling mechanism.

              VED-12 has two main types. One is Draw-out type. Model No. is VED-12D. The other is Fixed type. Model

              No. is VED-12F.

              Phase distance 150mm , 210mm and 275mm.

              Above choice all could be solid embedded pole type.
