The supply is fed to the circuit breaker via the disconnecting module.
A connector which can only be removed when the circuit breaker is
switched off isolates the circuit breaker from the power system on 3
poles.
The shock-protected isolation position is easily visible and is secured
by a padlock to ensure that the connector cannot be used during
maintenance work, for example.

The circuit breakers can be opened and closed via the remote-con-
trolled mechanism by means of electrical commands. This enables a
load or system to be disconnected from and then reconnected to the
power system from an operator control panel.
The circuit breaker can be disconnected from and reconnected to the
remote-control mechanism in situ.
Rotary switch

the door
The rotary switch extension for the door consists of a knob, a drive
coupling and an extension shaft. They comply with IP 65. The door
interlock prevents the cubicle door being opened inadvertently when
the switch is in the on position. The off position can be secured with
a maximum of 3 padlocks.
