FN12-12 / 630A; FN12-12R / 630A
    , FN12-12R / S400A, suitable for AC 50Hz.6kv or 12kv network, as breaking and closed load and overload current purposes, can also be used to break and close no-load long-term. No-load transformer and capacitor switch. 2, the load switch can be equipped with CS3 or CS2 type manual operation mechanism to operate. 1, FN12-12 / 400A, FN12-12R / 400A, FN12-12R / S400A,
    FN12-12D / 630-20 type indoor AC high voltage load switch (hereinafter referred to as FN12-12D load switch) is rated voltage of 12KV, rated
    
    Frequency of 50Hz three-phase high-voltage switching devices for the separation of load current, closed-loop current, no-load transformer and cable charging current, close the short-circuit current. Equipped with ground switch load switch, can withstand short-circuit current. FN12-12D.R / 120-31.5 type indoor AC high voltage load switch -
    
    - fuse combination (hereinafter referred to as FN12-12D.R combination of electrical) is FN12-12D load switch off with S □ LAJ-12 (XRNT □ -12)
    
    High-voltage current-limiting fuses are combined with the indoor high-voltage switchgear. It can reliably break any current until the short circuit current: the load switch is on
    
    Breaking the operating current, the fuse breaking short-circuit current, the joint breaking current and the short-circuit current between any over-current, while the fuse through its
    
    The impactor opens the load switch.
    Ordering instructions
    Order should indicate the following items:
    1, the type of load switch, name, quantity.
    2, if the fuse, please specify the fuse type, rated voltage, rated current.
