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.

INFORMATION
Recommended cross section
The values are only recommendations. They are no substitute for detailed project planning of the cables depending on the concrete application and considering the applicable regulations.
INFORMATION
Securing the supply system cable
- Secure the supply system cable with appropriate safety elements.
- When selecting the supply system cable, make sure that the selected cross section is in the range of the connectable cross section of the terminals.
