Using the data below, it is possible to determine the permissible current for a
prefabricated connection between a vertical Masterpact NT06/NT16, fixed or
drawout, 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 drawout Masterpact NT16 , 4P, where the ambient temperature around the
switchboard is 35°C and the IP > 31: the maximum permissible current for the
prefabricated connection (04492) is 1380 A.
Note:
the values indicated above have been validated for Prisma P switchboards.
