Maximum physical terminal content depends on the terminal dimension and
the maximum permissible cable size used.
Note:
Maximum pennissible rated current of the applied tenninals and cables must be laken
into account. Cables used intemally must be suitable for a temperature between 70° and 80°C.
For largeT cables, the number of conduetors must be advised by the manufacturer ( with Power
Dissipation Test Report ).
When using the table above, de-rating factors or nominal rated currents in accordance with
IEC 439 should be used.
Different types of terminals can be used together by utiJising the tabular values proportionally.
