4.3.3 Interlock for circuit-breaker/load-break
switch opening button
The interlock on the opening button is to prevent the switch
from being unintentionally opened. Once this interlock is in
place, the flap in front of the opening button can no longer
be lifted. The switch can no longer be switched off
manually. However, switching off by the protective relay, if
fitted, or the optional remote control remains possible. This
interlock can be applied in every position of the panel.
Installation is as follows:
Hook a padlock (19) through the hole below the opening
button, see Figure 4-14.
A paslock with a hasp of 1
– 12 mm can be applied.
4.3.4 Interlock for end position
This interlock is intended to prevent the unintentional
closing of the switch and operation of the change-over
switch.
When the interlock is in place, the operating handle cannot
be inserted in the control points. However, turning off via
the opening button and by the protective relay of the circuit-
breaker remain possible.
Installation is as follows:
1. Turn the selector (7) anticlockwise until the switch
control point is revealed.
2. Fit the scissor-type interlock (21) in control aperture,
see Figure 4-15.
3. Engage the scissors so that the openings are aligned.
Pass a padlock (19) through both holes, see
Figure 4-16.
