Embodiment Construction
[0084] see first Figure 10 . This figure shows the spring operating lever 10 with the associated clamping spring 20 installed in the clamp receiving space 32 of the installation switching device 30 and in the rest position. The installation switching device 30 may be a line protection switch, a main switch, a motor protection switch or the like. Its insulating casing is drawn schematically. The insulating shell includes a front face 31 , a rear face 33 , a front narrow face 34 , a rear narrow face 35 and a fastening face. Likewise, there is a broad face connecting the front and narrow faces parallel to the drawing plane, but in the case of Figure 10 is not drawn in the view. exist Figure 5 The wide face is drawn in the stereo view of .
[0085] The installation switching device 30 is generally used to monitor and / or switch on a current path passing between two terminal clamps. For this purpose, further components and elements are provided inside the installation swit...

The invention relates to an installation switchgear having a housing, having a front and a rear front side, a mounting side, front and rear narrow sides and broad sides, and having a screwless spring-loaded terminal in a fixed position inside a terminal connection space of the housing, said terminal comprising a terminal spring having a contact leg, a clamping leg having a clamping window comprising a clamping edge, and a curved spring back connecting the contact and clamping legs, said terminal working together with a carrier part comprising a terminal strip such that a connecting conductor can be connected between the back side of the terminal strip and the terminal edge. A spring actuation lever that can be actuated from outside the housing is pivotally connected to the housing, said lever when pivoted out of a rest position into an opening position pressing with a bending arm on the spring back such that the clamping window exposes a clamping opening on the rear side of the terminal strip for introducing a connecting conductor.
Description
technical field [0001] The invention relates to a mounting switchgear according to the preambles of the claims. Background technique [0002] Such installation switchgear may for example be a line protection switch, a fault current protection switch, a motor protection switch or a selective mains protection switch. Normally, opening a spring clamp device requires a tool by means of which pressure is applied to the spring blade. Then, although the spring clamp device itself is of very simple design, additional operating openings are provided in the housing of the mounting switch device, and the handling is complicated by the need for tools for inserting or removing the connecting wires. In order to be able to connect or reconnect the connecting lead to such a spring clamp with the use of a tool, the spring clamp device must include a spring operating device, by means of which the operator can open it by applying pressure to the spring leaf if necessary spring clip. When th...
