* The installer must comply with all local standards. The cable section must be suitable for the
installation method, the type of cable insulation and the cable length.
These values are provided for information purposes only. They must be verified and adapted
in relation to existing standards.
These values may vary in relation to the type of installation and the choice of conductors.
Comments:
This data is given for the most unfavourable installation in terms of maximum current
