Product Description

 

High Voltage Vacuum Load Switch Fn12-12 Series Switch Fuse Combination
FN12-12D630-20 type indoor high-voltage alternating-current load switch  is a three-phase high-voltage switching of rated voltage 12KV and rated  frequency 50Hz,used for making and breaking load current,closed loop current,no-load transformer and cable charging current, and making short-circuit current.It is able to withstand short-circuit current after being equipped with load switch of earthing switch.
FN12-12D.R/100-31.5 type indoor high-voltage alternating-current switch-fuse combination is an indoor high-voltage switchger made up of FN12-12D load switch and S LAJ-12 high-voltage  current-limiting fuse.It is able to breakany short-circuit current reliably working current and full short*circuit curent by combination unit,meanwhile,the load switch can be opened by fuse through striker.
