Locking provision for racking rails
The locking provision prevents the insertion of a circuit breaker in the guide frame. For this
purpose, the racking rails are locked with padlocks so that they cannot be pulled out again.
Activation
In order to activate the locking provision, once the circuit breaker has been removed, the
racking rails are completely inserted into the guide frame and secured in this position with
padlocks.
The locking provision for the racking rails is installed at the factory as standard. Padlocks are
not included in the scope of supply.
