An electrical switchgear cabinet is includes two side wall parts and a respective cover and base wall part. The wall parts are in each case integrally connected to one another, and form a rectangular frame which can be connected to a rear face and to a front face. Each side wall part and each cover or base wall part is angled along its outer edges so as to form a box-like shape. The angled edges are integrally connected to one another at the abutment points with adjacent angled outer edges and form a corner profile at each frame corner. As a result, it is possible for a connecting profile to be connected to the corner profile in each case. A switchgear cabinet connecting profile of the abovementioned type for connecting at least two switchgear cabinets (e.g., in a force-fitting manner) is also provided.
