Recommended cross section for nominal operation
The cross section of the supply system cables must be dimensioned based on the nominal line current Iline.
SEW‑EURODRIVE suggests the cable cross sections listed in the table. Cables with these cross sections can be used if the following conditions are met:
- The conductors are made of copper with PVC insulation.
- The cables are routed in cable ducts according to IEC 60204-1 installation type C at an ambient temperature of 40 °C.
