Rating data of the cable feeders for fuse-switch-

Rating data of the cable feeders
Tab. 6/10 and Tab. 6/11 states the installation data of the
switching devices if used in fixed-mounted cubicles with a
front door. The thermal interaction of the outgoing feeders
in the cubicle has to be and is considered by specifying the
rated diversity factor (RDF):

Rated current with fuse link = nominal device current
For the outgoing 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
For cubicles with a very high packing and/or power density,
a project-specific assessment is recommended. More
detailed information is available via your Siemens contact.
