Abstract
An installation switching device having an insulating material housing with a front face and an attachment face connected by two broad faces and an input and an output narrow face; an input terminal; an output terminal, wherein a current path runs from the input terminal to the output terminal; a switching mechanism configured to open or close a main contact point so as to switch the current path off and on, respectively, the switching mechanism having a switching handle configured to operate the switching mechanism; and at least one phase connecting rail disposed in an interior of the housing close to and parallel to the attachment face and electrically and mechanically isolated from other components and assemblies in the housing.

An installation switching device comprising:
- an insulating material housing having a front face and an attachment face connected by two broad faces and an input and an output narrow face;
- an input terminal;
- an output terminal, wherein a current path runs from the input terminal to the output terminal;
- a switching mechanism configured to open or close a main contact point so as to switch the current path off and on, respectively, the switching mechanism having a switching handle configured to operate the switching mechanism;
- and
- at least one phase connecting rail disposed in an interior of the housing close to and parallel to the attachment face and electrically and mechanically isolated from other components and assemblies in the housing, the phase connecting rail including a free end and a clamping contact disposed at the free end, the clamping contact projecting out of the housing on the attachment face and configured to clamp a busbar in an installation distribution block, wherein the phase connecting rail is connectable to the input terminal in an installed state.
An installation switching device comprising:
- an insulating material housing having a front face and an attachment face connected by two broad faces and an input and an output narrow face;
