Masterpact NT06 to NT16,
vertically mounted
DD383666
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 busbars depending on the ambient temperature around the
switchboard and the IP value.

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 Plus switchboards.
