Retracting the circuit breaker
CAUTION
Risk of injury due to circuit breaker falling
Take suitable precautions to be able to remove the circuit breaker safely.
1. Insert the racking handle, see Section "Inserting and removing the racking handle" above.
2. Move the circuit breaker into the DISCONNECT position.
3. Operate the side locking lever above the racking rail and remove the circuit breaker from the
guide frame.
Removing the racking handle
1. Pull the racking handle out.
2. Fold the handle back into line and return the racking handle to its storage compartment.
Locking the guide frame – interlocking the shutter
In order to safeguard an installation and its sub-distribution board in a no-current condition (e.g.
in the event of maintenance work) or until a new device is available to replace the device after
a delay, it is possible to achieve a simple and easily visible disconnection of the system by
removing the circuit breaker from the guide frame. In the meantime, undesired insertion of a
circuit breaker into the guide frame can be reliably prevented by padlocks on the shutter, see
diagram below.
