Functional description:
Same as the rocker switch but with a more powerful cam-operated switch. The cam-operated switch is equipped with a 0-position between the two directions of rotation. With this model the motor is switched off at the 0-position of the cam-operated switch each time the direction is reversed.
Version 2:
Special features:
- Automatic triggering of the power contactor when the direction is reversed
- Powerful model
- Compact design
Technical data:
- Designation
- L-O.u-R

2. Version
20 A 4.0 kW 400 V/AC-3; 2.2 kW 230 V/AC-3
Use for Series: K3000 3Ph - Function
- Winding reversal with self-holding interrupt in 0-position
- Actuation
- Wing handle
Circuit diagram [pdf-File]
Functional description:
The function is the same as with version 1 except that the self-holding circuit of the undervoltage trigger is interrupted as well at 0-position each time the direction is reversed. This means that the switch has to be switched on again each time the direction is reversed. This saving in time enables drives to be reversed with less material stress.
