Notes on the technical data
Current, voltage and power figures in these tables are rated values.
The cables to the device are protected by fuses of operating class gG.
The cable cross-sections have been determined for three-core copper cables routed
horizontally in air at 40° C ambient temperature (according to DIN VDE 0276-1000 and IEC
60364-5-52) with a permissible operating temperature of 70° C (e.g. Protodur NYY or
NYCWY) and the recommended conductor protection according to DIN VDE 0100 section
430 and IEC 60364-4-43.
Note
Cable cross-sections
When the conditions differ from the above stated (cable routing, cable grouping, ambient
temperature), the following instructions for routing the cables must be taken into account:
The required cable cross-section depends on the amperage which flows through the cable.
The permissible current loading of cables is defined, for example, in DIN VDE 0276-1000
and IEC 60364-5-52. It depends partly on ambient conditions such as temperature and partly
on the type of routing. If the cables are routed individually, they will be cooled relatively well.
If several cables are routed together, they may heat each other up. Please note the
corresponding derating factors for these supplementary conditions in DIN VDE 0276-1000
and IEC 60364-5-52.
