max. number of terminals depending of the above mentioned enclosure size and
the cross section resp. max. permissible conductor cross section of the built-in
terminals
Notes
1) Each incoming conductor and each internal connection wire is counted as a conductor.
Bridges and earthing conductors are not counted.
2) additional conductors optional
3) to be specified by the manufacturer (including temperature rise test)
4) When applying the values of this table simultaneous factors or load factors to IEC 439 may be
considered. Mixed equipment with circuits of different cross sections and currents is possible if
the various values of the table are applied proportionally:
Example: cross section / mm² current / A number of utilization
(general) conductors
2,5 16 10 (of 30) = 33 %
16 50 12 (of 48) = 25 %
25 63 36 (of 90) = 40 %
total = 98 % < 100 %
