    • FZN21 Series Indoor Vacuum Load Break Switch

    FZN21 Series Indoor Vacuum Load Break Switch

    FZN21 series indoor M.V. Vacuum load break switch and its fuse combination are applied for 12kV, 24kV and 40.5kV, 50/60Hz power systems. It widely use for industrial and mining area, to cooperate for Ring Main Units and Terminals. It can distribute, control and protect the electric power. This product fulfill with the requirements of following standards:IEC 60265-1/FDIS,IEC 60420 , GB16926 , GB3804 . This model of switch was combined with frame, isolator, Vacuum interrupter, earth switch, spring mechanism. It has good breaking capacity, safety, and long electrical endurance. This model can break on load current, over load current, and after cooperate with XRNT fuse, that can break short circuit current and protect the equipment work under loss phase. There are visible fracture. There is interlock between isolator, V-LBS and ES, which can forbidden mis-operation.
