The derating curve shows which currents may flow continu-
ously and simultaneously via all possible connections when the
component is subjected to various ambient temperatures below
its upper limit temperature.
The upper limit temperature of a component is the rated
value determined by the materials used. The total of the ambient
temperature plus the temperature rise caused by the current
load (power loss at contact resistance) may not exceed the
upper limit temperature of the component, otherwise it will be
damaged or even completely ruined. The current-carrying
capacity is hence not a constant value, but rather de-creases
as the component ambient temperature increases. Furthermore,
the current-carrying capacity is influenced by the geometry of
the component, the number of poles and the conductor(s)
connected to it.
The current-carrying capacity is determined empirically accord-
ing to DIN IEC 60512-3. To do this, the resulting component
temperatures t
are measured for three different currents I
The values are entered on a graph with a system of linear
coordinates to illustrate the relationships between the currents,
the ambient temperatures and the temperature rise in the
component.

The loading currents are plotted on the y-axis, the compo-
nent ambient temperatures on the x-axis. A line drawn
perpendicular to the x-axis at the upper limit temperature t
of the component completes the system of coordinates. The
associated average values of the temperature rise in the
component, Δt
current I
generated in this way are joined to form a roughly parabolic
curve.
As it is practically impossible to choose components with the
maximum permissible contact resistances for the measure-
ments, the base curve must be reduced. Reducing the currents
to 80% results in the “derating curve” in which the maximum
permissible contact resistances and the measuring uncertainties
in the temperature measurements are taken into account in
such a way that they are suitable for practical applications,
as experience has shown. If the derating curve exceeds the
currents in the low ambient temperature zone, which is given
by the current-carrying capacity of the conductor cross-
sections to be connected, then the derating curve should be
limited to the smaller current in this zone.
