Using the data below, it is possible to determine the permissible current for a
prefabricated connection between a vertical Compact NS630b/NS1600, fixed or
withdrawable, and Linergy busbars depending on the ambient temperature around
the switchboard and the IP value.

Example
For a fixed Compact NS1600, 4P, where the ambient temperature around the
switchboard is 35 °C and the IP > 31
:
The maximum permissible current for the prefabricated connection (04488) is 1450 A.
Note:
the values indicated above have been validated for Prisma Plus switchboards.
