Switches
The state of the circuit breakers can be determined by the position of the
switches:

Locking the circuit
breakers
You can prevent the circuit breaker from being switched on by unauthorized
persons by securing the switch drive (toggle switch or rotary switch) with a
padlock (shackle diameter 3.5 to 4.5 mm).

Reclosing after a tripping operation
After the circuit breaker has been tripped, the switch goes into the tripped
position to indicate this. You use the switch to close the circuit again.
In the case of frame sizes S0 to S3, the rotary switch must be put in the
OFF position manually before it is switched on again to avoid switching to
the fault inadvertently.
In the case of frame sizes S2 and S3, it is possible to switch on and off using
a motorized remote-control mechanism (see Section 2.4, Accessories).
