3.7 Fuses and cable cross−sections
Field Description
Fuses and cable cross−sections All information given in this chapter are recommendations.
They refer to
l controllers installed in control cabinets.
l cables with a distance to the wall which is at least as wide
as the cable cross−section.
l a max. ambient temperature of +40 °C.
Selection of the cable
cross−section
Consider the voltage drop under load (£ 3 % acc. to
DIN 18015 part 1) for the selection.
Protection of the cables on the
AC side (L1, L2, L3)
On the AC side, the cables are protected by means of common
fuses.
Fuses in UL−conform plant must have UL approval.
Protection of the cables on the
motor side (U, V, W)
It is not necessary to fuse the motor cable.

Standards and regulations The user is responsible for the compliance with national and
regional standards and regulations (e.g. VDE 0113, VDE 0298,
EN 60204).
3.7.1 Mains supply
For fusing the mains supply you can use the following fuses (gRL) and cable
cross−sections:
