| Rated voltage | 40.5kV |
| Series | FKN12-12/24/40.5kV |
The switch disconnectors series FkN12 are increasingly adopted in MV instalations,owing to their superior interrupting features and to their
capability to withstand the short-circuit currents which occur mainly as consequences of faults in distribution networks.Theversionscombined with HRC
fuses are particularlysuitable fortheprotection of distribution transformers upto1250kVA
The use of FKN12,designed for installation in compartmented switchboards have the following advantages:
-Fullsegregation between the busbar compartment and the cable compartment, with switch disconnector in both'closed” and"open' position.
The moving contact,of the sliding vertical type,can be easily checked and cleaned with live bus-bars and earthing switch (ES) closed.
- No adjustment is needed in the trpping mechanism of the switch fuse combination and of the ES:they are built together in a single unit,which is
adjusted andchecked during assembly in the factory,before the final test.
