Recommended cable
for three-phase
connections
Calculate the current in the connecting cable to determine cable cross section.
The applicable guidelines must be followed when determining cable cross
sections.
If fuses are placed on the input side only when transformers are used, then
protect the secondary line against short-circuiting.
Ready-made INDRAMAT cables are available as connecting cables for the
DDC 1.2 The recommended cable types and cross sections apply where
INDRAMAT transformers and fuses are used.
The cable recommended in the following table has a current capacity as per
EN 60 204 (VDE 0113) – E mode of installation.
