Installation
Due to the special shape of the mounting holes on the 3TM vacuum contactor , it is
possible to position it safely on loose, pre-assembled screws.
Mount the 3TM vacuum contactor tension-free and torsion-free at the four specified
mounting points (*) on a frame, wall, or on a withdrawable part.
Mounting screws M10, resistance 8.8, tightening torque 48 Nm
Note
Transporting the vacuum contactor
Transporting the vacuum contactor by holding and lifting the auxiliary switches on
the sides leads to material damage.
Only transport the vacuum contactor by holding it under the operating mechanism
box, the base plate, or the pole shells (see “Transport to the installation site”,
p. 9).
Note
Attaching the vacuum contactor
Attaching the vacuum contactor with shear, tensile, or compressive stresses can
lead to material damage.
Attach the vacuum contactor by the specified mounting points without shear, ten-
sile, or compressive stresses.
