Detail Information

Draw out type VED-12KV 1250A 25KA VCB vacuum circuit breaker with copper parts 210mm phase distance replace of VD4

Vacuum Circuit Breaker accept customized order according to technical drawing or samples.
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.
