Abstract
An electrical service device having a housing is disclosed, in which voltage-carrying components are accommodated which are accessible via openings in the housing of the service device. At least one opening can have at least one wall-like insulating barrier associated with it which consists of an electrically insulating material and with which it is possible for the air gaps and leakage paths between two adjacent openings to be increased. The insulating barrier can be fixed to the housing of the service device.
Claims19
An electrical service device comprising:
- a housing that includes plural openings;
- voltage-carrying components located within the housing, wherein the voltage carrying components are accessible via the openings in the housing;
- narrow side walls;
- at least one facing wall;
- and
- broad side walls,
- wherein at least one of the openings has a wall-like insulating barrier,
- wherein the insulating barrier includes an electrically insulating material,
- wherein the insulating barrier is fixed to the housing of the service device, and
- wherein two depressions are provided on the broad side walls in the region of the openings such that, when two service devices are arranged next to one another in a row, in each case one gap is formed between the second depressions, which gap opens in each case towards the facing walls and the narrow side walls or opens out into them, with the result that the air gaps and leakage paths are increased.
