Embodiment Construction
[0165] Think first Figure 1 to Figure 5 . see figure 1 , a mounting switchgear 1 according to the invention has a housing 3 of insulating material formed by joining together two housing parts 2, 2' along a separating plane 2a, the housing 3 having a front side 4, a rear side 5, 5', fixed Or connect side 6, make front side 4 and back side 5,5' connect front narrow side 7,7', back side narrow side 8,8', and two wide sides 9 (in figure 1 Only one of them is shown).
[0166] Attached at the rear 5' in the terminal connection space within the housing 3 is a conventional screw terminal for connecting connecting wires, which is accessible through the terminal opening 11.
[0167] At the second rear side 5 , opposite the screw terminals, a terminal connection space 18 is provided, wherein the opening of the terminal connection space 18 is directed towards the housing wide side 9 , the rear narrow side 8 , and the rear side 5 . In the terminal connection space 18 there are two ter...

Abstract
The invention relates to a installation of switching equipment(1), which comprises a shell with a frontage (4), a back (5), a fixed side (6),a narrow positive side (7), a narrow back side (8), and a shell(3) of a wide side (9), two threadless terminal connections (10,10') in space where video connections (18) are fixed on the shell (3). Each video connection (10,10') is covered by a video coverage part(22, 22') with a video surface (24,24'),the video surface has a plurality of video openings (26, 26') and a plurality of guide devices (28, 28'), the video coverage part has a pleural area (29,29') which covers the video connection (10,10'). A reed actuating jack(30, 30')is molded on each video coverage part(22, 22'), whose structure can lead to the opening of the reed actuating jack bearing clip spring (12,12') when the coverage part(22, 22') whirls to the clip spring (12, 12').
Description
technical field [0001] According to the characterizing features of claim 1, the invention relates to an installation switchgear comprising a housing and two screwless terminal connections in each case comprising at least one clip spring for the connection of the connection conductors, which The terminal connection is fixed in the terminal connection space of the housing. Background technique [0002] Common installation switching devices contain in their housing at least one contact with at least one fixed contact part and one movable contact part, via which contact the current path from the input to the output can be opened and closed. The contacts are usually operated by a switching mechanism with a self-latching point. Common installed switchgears may also include tripping means such as thermal tripping or instantaneous tripping magnets, which act on the contacts or switching mechanism respectively to open the contacts when a short-circuit current or a fault current occu...
