Abstract

A switching cabinet having a rack with horizontal and vertical frame profiles. The horizontal frame profiles form a lower and upper frame and the vertical frame profiles are secured in the comer areas of the upper and lower frames. The vertical frame profiles are symmetrical to cross-sectional diagonals running across virtual, vertical outer edges of the rack. Greater flexibility in installing built-in fixtures inside the switch cabinet is achieved by providing the vertical frame profiles which are turned towards the inside of the switching cabinet with an open inner cavity having two inner walls extending in the longitudinal direction of the profiles so that vertical assembly rails can be mounted in the inner cavity, one profiled side standing perpendicular to the outside of the rack is joined to the inner walls. The inner walls, the assembly racks and the profiled sides can have rows of fastening cavities inserted according to a division grid.

Dependent claims

In a switching cabinet with a rack having horizontal and vertical frame profiles (11, 12, and 30), where the horizontal frame profiles (11, 12) form a lower frame and an upper frame (10) and the vertical frame profiles (30) are attached in corner regions of the lower frame and the upper frame (10), where the vertical frame profiles (30) are symmetrical to a cross-sectional diagonals running across virtual vertical outer edges of the rack, where the vertical frame profiles (30) turned towards a inside of the switching cabinet have an open inner cavity (35.1), where vertical assembly rails (50) can be mounted in the inner cavity (35.1), where one profiled side (31, 32) perpendicular to an outside of the rack is joined to inner walls, and where the inner walls (33, 34), the assembly rails (50) and the profiled sides have rows of fastening cavities (56, 57) inserted according to a division grid, the improvement comprising:

the inner walls (33, 34) and the profiled sides (31, 32) having rows of attachment cavities (37, 37.1) installed in the division grid.
