Assembling the panels
110-0084.9 / 15 NXAIR / ≤ 40 kA 79
Busbar version with insulation on contactor panels with panel width 435 mm
For panel versions with insulated busbar, insulating shells cover the joints of the busbar with the feeder bars,
and plastic tubes cover the horizontal bars from the busbar system.
The busbars are assembled like in panel versions with a rated voltage of U
r
≤ 12 kV (described above). Finally,
the insulating shells and plastic tubes are mounted additionally.
Damage to the switchgear panels
Insulating half-shells are supplied with the correct size for each panel.
Do always mount insulating half-shells on the joints of the busbars with the
feeder bars, on all phases L1, L2, L3.
Observe the positions of the busbar connection with feeder bars in the end
panels and assemble the insulating half-shells accordingly.
The strip fasteners are reclosable and reusable.
Leave a protrusion of approx. 15 mm when shortening the strip fasteners.
The insulating half-shells have a different shape for the locking labyrinth on the
corners.
Press the insulating half-shells onto each other to interlock them together.
Attach the insulating shells in pairs at the bolted joint and fasten with the
strip fastener.
