Function
You can secure the motor starter protector against unauthorized closing, for example, if
repair work needs to be carried out.
Procedure
Move the rotary switch to the OFF position. Take the cylinder out of the rotary lever. (This
locks the rotary operating mechanism.) Secure the motor starter protector against
unauthorized closing by locking the rotary switch with a padlock (shackle diameter 3.5 to
4.5 mm).

4.8.5 Reclosing after tripping
Tripping
When the motor starter protector trips, the rotary switch moves to the tripped setting to
indicate that it has tripped.
An option is available (in the form of an accessory) to have a signaling switch report tripping
electrically.
Reclosing
Reclosing takes place directly on the switch. The rotary operating mechanism has to be set
to O first before reclosing, to return the mechanism to readiness for operation. The motor
starter protector can then be reclosed.
