Abstract: Disclosed is a receiving and securing device for keystone modules, consisting of at least two components which are releasably connected to each other and which delimit a securing gap therebetween, of which the free gap space can be modified by an advancing movement of the second component towards the first component, and at least the first component, around which the second component engages, delimits a free opening space with a securing option for the latching engagement of a keystone module that can be inserted into the opening space.

Abstract: An air conditioning arrangement, in particular a cooling arrangement, includes a switchgear cabinet (1) having a supporting device (4). Electric and/or electronic devices (2) to be air-conditioned are disposed in rows on top of and next to one another on the front side (17) of the supporting device (4). The front side (17) faces the doors of the switchgear cabinet. The devices (2) in the switchgear cabinet (1) can be at least partially air-conditioned by at least one heat sink (50), forming an autonomous component.

Abstract: A mounting system (1) includes in switchgear cabinets a horizontal mounting strip (3) with a front face to which an electrical device (2) can be secured. The mounting strip (3) has a locking flange (63) on its rear side lying opposite the device (2) that is to be secured. The locking flange, onto which another component (65) of the mounting system (1) can be directly locked or can be indirectly secured by a lockable adapter element (66), extends in the longitudinal direction of the mounting strip (3).

Abstract: A mounting system (1) for arranging electric devices (2), for example switchgear cabinets, includes at least one preferably horizontal mounting strip (3) to which at least one device (2) can be secured. The mounting strip (3) includes a support rail (6) to which the device (2) can be releasably fastened and located in a first section (41) of the mounting strip. The first section is central in relation to a cross-sectional view through the mounting strip (3), transversely to its longitudinal axis. A third section (43) of the mounting strip located at a distance from the support rail (6) is at a greater vertical distance (44) from the bottom point (39) of the support rail (6) than a second section (42) at its end that is closer to the support rail (6), especially its end adjoining the support rail (6). The second section is located between the first section (41) and the third section (43).

Abstract: A mounting system (1) arranges electric devices (2), in switchgear cabinets. The mounting system (1) includes horizontal mounting strip (3) to which a device (2) can be secured. At one of its longitudinal edges, the mounting strip (3) includes a receiving device (20) extending along the longitudinal axis of the mounting strip and receiving components (7, 8, 9, 10, 11). The receiving device (20) has locks (22, 23) to be interlocked with an associated lock (26) of the component (7, 8, 9, 10, 11) inserted into the receiving device (20). Depending on the design of the associated lock (26) of the component (7, 8, 9, 10, 11), the interlocking action can be cancelled exclusively by a pulling force acting on the additional component (7, 8, 9, 10, 11) or cannot be so cancelled but is self-locking.

Abstract: The invention relates to a mounting system (1) for arranging electric devices (2), for example, especially in switchgear cabinets. Said mounting system (1) comprises at least one preferably horizontal mounting strip (3) to which at least one device (2) can be secured. The, mounting strip (3) includes a support rail (6) to which the device (2) can be releasably fastened and which is located in a first section (41) of the mounting strip, said first section being preferably central in relation to a cross-sectional view through the mounting strip (3), transversely to the longitudinal axis thereof.

Abstract: An apparatus (10) for arranging and fastening electrical units (152, 154, 156), in particular in a switch gear cabinet (1), has a mount element (14). On the fitting side of the mounting element, a module mount (150) with at least one electrical unit (152, 154, 156) can be fastened. The mount element (14) has a groove (16) extending in a longitudinal direction and open towards the fitting side. The module mount (150) can be suspended in the groove in an optional position in the longitudinal direction of the groove (16). The groove (16) is shaped such that, owing to the force of the weight acting on the suspended module mount (150), the module mount (150) is arranged on the mount element (14).

Abstract: The invention relates to an apparatus (10) for arranging and fastening electrical units (152, 154, 156) in particular in a switchgear cabinet (1), wherein the apparatus (10) has a mount element (14), on the fitting side of which it is possible for a module mount (150) with at least one electrical unit (152, 154, 156) arranged thereon to be arranged and fastened, characterized in that the mount element (14) has a groove (16), which extends in a longitudinal direction and is open towards the fitting side and in which the module mount (150) can be suspended in an optional position in the longitudinal direction of the groove (16), and in that the groove (16) is shaped in such a way that, owing to the force of the weight which acts on the suspended module mount (150), the module mount (150) is arranged on the mount element (14) and is secured against falling down from the mount element (14), and to a fitting system with such an apparatus (10).
