Recommended cross section
The cross section of the supply system cables must be dimensioned based on the nominal line current Iline.
SEW-EURODRIVE suggests the following cable cross sections. These cable cross sections apply under the following conditions:
- The conductors are made of copper with PVC insulation, operating temperature 70 °C.
- The cables are routed according to IEC 60204-1 installation type C at an ambient temperature of 40 °C, accumulation 1.

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.
- When selecting the line fuse, observe chapter Line fuses and miniature circuit breakers.
