Product Detailed

Isolate Switch
1.Type:FZN25
2.Standard|:IEC GB
3.Main Material:Procelain&Steel

  Overview
       FZN25, FZRN25 vacuum load switch combination units, for three-phase AC 50Hz ring network power and industrial power equipment for load control and short circuit protection purposes, load switch division and load, closed Loop current, no load transformer cable charging current. Switchgear can be up to the rated short-circuit breaking current of any current. Fracture separation using direct-action and vacuum arc chamber linkage. With manual and electric functions.
      FZN25, FZRN25 unique structural design of transmission, interr upter only when closing and withstand high pressure breaking the moment, so small and light weight.
     FZN25, FZRN25 isolation can be achieved and the interr. upter Fracture Fracture A Times of operation.
      FZN25, FZRN25 static contact with the moving contacts in the lead torch switch between each other linked with the earth ground valve, ensures safe and convenient maintenance.
