Features
• Combination of power area and signal area in the
same connector
• Axial screw termination for power area
• Cage clamp termination for signal area
• Finger safe
• Same range of wire gauge for PE contact and
power contacts
Assembly instructions see page 05.22
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.
