    • FZN25-12 Indoor Medium Voltage Vacuum Load Break Switch

    FZN25-12 Indoor Medium Voltage Vacuum Load Break Switch

    FZN25-12D/T630-20 Indoor AC medium voltage vacuum load break switch is three-phase AC 50/60 Hz, rated voltage 12kV indoor installation, which is suitable for using in industrial and mining situation and so on enterprise substation and transformer and cable charging current. It had manual and motor operating mechanism that is advantageous to realize remote control. FZRN25-12D/T[]-31.5 indoor AC medium voltage vacuum load break switch with fuse combination, The versions combined with HRC fuses are particularly suitable for the protection of distribution transformers up to 1250 kVA, to break fault current and over load current.
