Han ® K 4/0, Han ® K 4/2
Features
• Combination of power and signal area in one
connector
• Screw termination for power and signal area
• Missing signal contacts for Han ® K 4/0
In accordance with the appropriate regulations a wire-end
sleeve has to be used at clamps without wire protection
(see „Screw terminal“, chapter 00).
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.
