Label for installed internal accessories
You can make a note of the number of installed accessories on the internal accessories label.
Accessories that have been pre-installed in the factory are already listed here.
This tells you which accessories are installed without the need to open the circuit breaker.
You can use this information, for example, to reorder components.
If there is a metering function provided, it is possible to see here on which side of the main
contacts the voltage tap is located (above/below or on the incoming/outgoing side).

A label is axed to the left-hand side of the circuit breaker that provides an overview of the most
important data of the circuit breaker.
Label for guide frame
A label is axed to the left-hand inside of the guide frame that provides an overview again of the
most important data of the guide frame.
