Embodiment Construction

[0070] figure 1 A first closure device 20 according to the invention for a plug-in frame of an electrical plug-in switching device is schematically shown in a perspective view. The first closing device 20, which is preferably designed as a closing slide, has a handle 21 which can be gripped by the user in order to position the first closing device 20 relative to the first side wall 2, in particular the first side wall, of the plug-in frame. 2 frontal 3 movements. In addition, the first closure device 20 has a locking element 23 , by means of which the first closure device 20 can be held on the first side wall 2 , in particular on the inner side 9 of the front side 3 of the first side wall 2 . in a certain location. Preferably, the locking element 23 is arranged on the first closing device 20 in such a way that it enables, when the recess 22 of the first closing device 20 is aligned with the guide 8 on the first side wall 2 of the plug-in frame When correctly arranged, the f...

Abstract

The invention relates to a plug-in frame for an electrical plug-in switchgear, in particular a plug-in circuit breaker, comprising: an adapter base for electrically connecting the plug-in switchgear to an energy supply device; a screw , for lowering and lifting the plug-in switchgear relative to the plug-in frame; the crank (1) for actuating the screw; the first side wall (2), for laterally holding the plug-in in the plug-in frame type switchgear, wherein the first side wall (2) has on its front side (3) a crank opening (4) for the crank (1) to be guided through the first side wall (2) to the screw, wherein the first closed The device (20) serves to release or at least partially cover the crank opening (4), wherein the first closing device (20) can be actuated manually or via a plug-in switching device.

Description

technical field [0001] The invention relates to a plug-in frame for an electrical plug-in switchgear and to a unit consisting of a plug-in frame and an electrical plug-in switchgear. Background technique [0002] The task of electrical switching devices, such as circuit breakers, is to disconnect one or more loads from the power supply network in the event of a specific fault. A common fault is the occurrence of a short-circuit current, and circuit breakers are generally designed to move the switching element and thus decouple the connection between the load and the supply network when such a short-circuit current occurs. [0003] The invention relates to a plug-in frame for an electrical plug-in switchgear, in particular to a plug-in circuit breaker in the low-voltage range. "Low voltage" typically refers to voltages up to about 2000 volts. With a corresponding design of the switching isolation section, such a switching device can also be used for switching voltages of mo...
