* Table specifies enclosures with wall thickness of 120 mm. In case of enclosures with a wall thickness of 90 mm, subtract 60 mm from the external dimensions of the enclosure.
** Technical parameters are specified as maximum, they will depend on the configuration of the substation and on devices used.
*** Detailed selection of switchgears and their equipment is listed in chapters dedicated to individual devices in the catalogue.
