Current carrying capacity
Current carrying capacity
The current carrying capacity is determined in tests which are
conducted on the basis of the DIN IEC 60 512 part 5 . The current
carrying capacity is limited by the thermal properties of materials
which are used for inserts as well as by the insulating materials .
These components have a limiting temperature which should not
be exceeded .
The relationship between the current, the temperature rise (loss
at the contact resistance) and the ambient temperature of the
connector is represented by a curve . On a linear co-ordinate
system the current lies on the vertical line (ordinate) and the
ambient temperature on the horizontal line (abscissa) which ends
at the upper limiting temperature .
In another measurement the self-heating (∆t) at different currents
is determined .
At least 3 points are determined which are connected to a parabolic
curve, the basic curve .
The corrected current carrying capacity curve is derived from this
basic curve . The reasons for the correction are external factors
that bring an additional limitation to the current carrying capacity,
i .e . connectable wire gauge or an unequal dispersion of current .

Depiction in accordance with DIN EN 60 204 for PVC-insulated copper wires in an ambient temperature of + 40 °C under permanent operating conditions .
For different conditions and temperatures, installations, insulation materials or conductors the relevant corrections have to be carried out .

Definition: The rated current is the continuous, not interrupted
current a connector can take when simultaneous power on all con-
tacts is given, without exceeding the maximum temperature .
Acc . to IEC 61 984 the sum of ambient temperature and the tem-
perature rise of a connector shall not exceed the upper limiting
temperature . The limiting temperature is valid for a complete con-
nector, that means insert plus housing .
As a result the insert gives the limit for the temperature of a com-
plete connector and thus housings as well .
In practice it is not usual to load all terminals simultaneously with
the maximum current . In such a case one contact can be loaded
with a higher current as permitted by the current capacity curve, if
less than 20 % of the whole is loaded .
However, for these cases there are no universal rules . The
limits have to be determined individually from case to case . It is
recommended to proceed in accordance with the relevant rules of
the DIN IEC 60 512 part 5 .
