Panels with motor operating mechanism control
404 NXAIR / ≤ 40 kA 110-0134.9 / 14
The procedure for opening the circuit-breaker manually in panels with motor operating mechanism control is
identical with the procedure in panels without motor operating mechanism control.
For opening the circuit-breaker manually, see chapter 10.13.
27.12 Closing the circuit-breaker manually
Closing the circuit-breaker manually is carried out by pushing a rod through an actuating opening in the high-
voltage door, thereby operating the ON pushbutton underneath the high-voltage door. In contrast to manually
opening the circuit-breaker, closing is only possible when the control door is open. However, the indicator for
the circuit-breaker position can still be seen through an inspection window after closing the control door.
