11 Gas compartments
Function The distribution of the gas compartments is decisive for working on 8DA10 switchgear during
operation and the resulting operational restrictions. In case of fault, the distribution of the gas
compartments determines the extent of work. The following example shows the distribution
of the gas compartments with the associated item designations of the manometers.
For further information, please contact the Siemens Service Hotline.

Gas quantity The gas quantity of 8DA10 varies depending on the pressure, panel connection version and
busbar component.
The gas quantities are determined specifically for the project, and are indicated on the rating
plates of the panels.
