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.
