Connection.

Horizontal link.

Using the data below, it is possible to determine the size of the copper bars and the

maximum permissible currents when making the connections to busbars for a

vertical, drawout Masterpact NW08/NW32, front or rear connection, taking into

account the ambient temperature around the switchboard and the IP value.
