Mounting the IP plate (optional)
The IP plate (internal arc protection plate) is a protective plate that separates the
high-voltage area from the drive area and provides additional protection in the event
of a fault arc.
The IP plate can also be mounted for vacuum circuit-breakers with withdrawable
parts.
• Cover remains mounted.
• Take the fixing elements out of the supplementary equipment and mount the IP
plates on both sides as shown in the installation drawing.
• Guide continuous IP plate between pole shell and operating mechanism box
and fix to the operating mechanism box.
• Tightening torque 24 ±2 Nm.
Note
The IP plates are classed as accessories.
Whether mounting is possible depends on the version of the switching device.
You can ask the manufacturer if mounting is possible.
When the IP plate has been mounted, it prevents access to the system side and
prevents injuries.
