Features
• Combination of power and signal area in one
connector
• Axial screw termination for power area
• Screw termination for signal area
Assembly instructions see page 05.23
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.
