Derating Curve:
The derating curve indicates the maximum current that can permanently and simultaneously flow through all connections if the
component is exposed to ambient temperatures below its upper limit temperature.
The upper limit temperature of a component is determined by the materials. The maximum temperature is calculated from the
ambient temperature and from heating due to current loading, it must not exceed the upper limit temperature of the component.
The derating of a component is not a constant value, but decreases hand-in-hand with the increase in component ambient tempe-
rature. Furthermore, current loading capacity is dependent upon geometry, the materials employed, the number of poles and the
conductor.
British and US comparative sizes for cables and lines

Since it is not advisable to use Heavy Duty connectors at
their loading limits, the base curve is reduced. If the loading
currents are reduced to 80%, then this produces the redu-
ced base curve in relation to the various connectors and
measurement uncertainties at which temperature measure-
ments are taken into account. Experience shows that the re-
duced base curve is a successful popular application.
NB: Only the reduced base curve is reproduced on the follo-
wing derating curves for inserts.
