Configuration
Mounting and fixing
The 3SB3 devices can be easily and quickly mounted:
• Actuators or indicator lights are positioned in the opening of
the front panel from the front
• Position the holder from the rear
• Tighten the screw on the holder
• Snap on the contact block or the lampholder directly onto the
actuator from the back
The holder for the round versions is set to a switchboard thick-
ness of 1 to 4 mm when delivered and is placed in the direction
of the arrow ↑ 1–4 mm ↑ on the actuator/indicator from the back.
The fixing screw is located underneath, on the right.
For a switchboard thickness of 3 to 6 mm, the holder is reversed
and mounted in the direction of the arrow at ↑ 3–6 mm ↑ and the
fixing screw is located on the upper right. In this case, the fixing
screw must be rotated anticlockwise to its limit before mounting
the holder.
The control panel depth of 1 to 4 mm can be compensated with
the holder for the square version.
When label holders, protective caps or similar accessories are
used, the greatest permissible control panel thickness must be
reduced by the wall thickness of the accessory part.
