Current carrying capacity
Current carrying capacity
The current carrying capacity of the connectors is limited by the
thermal load capability of the contact element material including
the connections and the insulating parts. The derating curve
is therefore valid for currents which flow constantly (non-inter-
mittent) through each contact element of the connector evenly,
without exceeding the allowed maximum temperature.
