Abstract: A switch cabinet arrangement having at least one switch cabinet frame and at least one multipole touch protection module which is mounted on a mounting plate in the interior of the switch cabinet frame and in which a plurality of busbars are accommodated in a touch safemanner and are accessible to device adapters via contacting passages, wherein the touch protection module has a modular housing with at least one central module or a plurality of central modules which are arranged in a row and are identical to one another, the at least one central module or at least one of the central modules being closed at its end facing a vertical outer edge by an end module which is aligned with the vertical outer edge of the mounting plate with its vertical end side or projects beyond the latter.

Abstract: A bus bar system having at least one bus bar which is accommodated in a contact-protection housing in a contact-protection manner and in an accessible manner via contacting passages for electrical devices and/or device adapters, the contact-protection housing having a lower part and an upper part which is detachably fixed on the lower part and between which the at least one bus bar is held, wherein the upper part has, on its side facing the lower part, a plurality of plug-in receptacles extending from the latter into the lower part, and the lower part has at least one slide with at least one latching pawl which can be adjusted between a locking position, in which the at least one latching pawl engages in the plug-in receptacle, and a release position, in which the at least one latching pawl is positioned in front of the plug-in receptacle. A corresponding method is further described.

Abstract: A busbar adapter has a mounting rail for attaching a switching device to the busbar adapter, wherein the mounting rail can be attached to the busbar adapter at different positions. The mounting rail includes leg elements and the busbar adapter includes passages through which a respective one of the leg elements of the mounting rail extend with a latch from a first boundary surface of the passages on which the mounting rail rests, to a second boundary surface of the passages, such that the respective latch of the leg elements is, with a retaining surface thereof, arranged in a distance to the second boundary surface which corresponds to a dimension of a slider positively insertable between the retaining surface and the second boundary surface.
