Installation 205
The rated current for semiconductor fuses is normally given by the fuse manufacturers for copper conductors
that have a current density in the order of 1.3 - 1.6 A/mm (IEC 2 69-4). This low utilisation results in extra
copper costs during the installation of high current systems, but helps to prevent overheating of the fuses.
Alternatively it is possible to use a fuse of a higher rating, and derate it for use in standard fuseholders and
installations. This derating factor is only applied to large fuses for the models PL/X 185/225/265. Hence the
fuses in the table for these models have been selected with a further derating to approx. 80 % in order that
they may be used in a standard fuseholder. No derating is required for installations that do comply with IEC
269-4, and in this case a smaller fuse could be selected in accordance with the recommendations given
above.
