Terminal Boxes
Series 8118/1, Series 8118/2
5.3
Internal Built-in Components
5.3.1 Ascertaining the maximum Number of Conductors
Equipping the terminal boxes
The maximum number of conductors depending on the conductor cross-section and the
number of loaded terminals for the temperature class T6 for Ta
(
40 °C or T5 for Ta
(
55 °C:
8118/112, 8118/114
8118/122, 8118/124
Heat develops due to contact resistance at the clamping units and due to the
electrical lines installed in the enclosure. In order to ensure that the maximum
permissible temperature of the enclosure is not exceeded, the current load of the
electrical circuits in the enclosure must not be too large!
