Recommended fuse calibres

Fuses recommended: SIBA brand with medium type

striker, conforming to IEC 60282-1 (Low loss fuses).

The values for combined fuses, in accordance with

IEC 62271-105, are greyed.

The fuse-switch assembly has been temperature-rise

tested under normal service conditions according to

IEC 62271-1.

A fuse-holder carriage adapted for 292 mm 6/12 kV

fuses is available.

For ratings not marked in bold the measurement is

442 mm.

If any of the fuses blows, we recommend changing all

three.

For overload conditions in the transformer or use of

other brands of fuse, please check with

Ormazabal

For the auxiliary services function, the recommended

fuse is "Back up" type 10/24 kV, 442 mm, calibre 2 A.
