max. number of terminals depending on the cross section or the max. permissible
conductor size of the terminals installed
Note
1) Every entered conductor and every internal connection wire counts as conductor.
Bridges and earth conductors are not counted.
2) additional conductors optional
3) When applying these tabular values, simultaneity factors or load factors
according to IEC 439 may be considered.
Mixed equipment with circuits with different cross sections and currents is possible
by proportional utilization of the different tabular values:
example: cross section / mm² current / A number of conductors utilization
(generally) 1,5 10 10 (of 16) = 63 %
2,5 16 4 (of 12) = 33 %
total = 96 % < 100 %
4) When mounting fuses ≤ 2 A ................... temperature class „T6“
When mounting fuses > 2 A bis ≤ 5A ..... temperature class „T5“
When mounting fuses ≤ 6,3 A ................ temperature class „T4“
