4.3.5 Ratings for cable feeders in SFD / HFD
Withdrawable units in SFD are applied up to a rated current
of 250 A. The two withdrawable unit variants SFD and HFD
can be mixed within one cubicle.
The thermal interaction of the feeders in the cubicle has to
be and is considered by specifying the rated diversity factor
(RDF):
Permissible continuous operational current (cable feeder) =
= rated current I

Tab. 4/17: Rated currents and minimum withdrawable unit heights for cable feeders in SFD / HFD
For the feeders in the cubicle, the rated diversity factor RDF
= 0.8 can be applied:
• regardless of the number of feeders in the cubicle
• regardless of the mounting position in the cubicle
Rated currents and minimum withdrawable unit heights for
cable feeders are stated in Tab. 4/17. For cubicles with a
very high packing and/or power density, a project-specific
assessment is recommended. Further information is availa-
ble from your Siemens contact.
