Power cable sizes and fuses

Cable dimensioning for rated currents (I
the corresponding fuse types for short-circuit protection of the input power cable.
The rated fuse currents given in the table are the maxima for the mentioned fuse
types. If smaller fuse ratings are used, check that the fuse rms current rating is larger
than the rated I
is needed, multiply current I
on page 23.
Check that the operating time of the fuse is below 0.5 seconds. The operating
time depends on the fuse type, the supply network impedance as well as the cross-
sectional area, material and length of the supply cable. In case the 0.5 seconds
operating time is exceeded with the gG or T fuses, ultra rapid (aR) fuses will in most
cases reduce the operating time to an acceptable level.
Note: Larger fuses must not be used.
