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 LGY busbars depending on the ambient temperature
around the switchboard and the IP value.

Connection impossible due to the operating-temperature limits of the devices installed in the switchboard.
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.
