Abstract: A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and are connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and are electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, are in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.

Abstract: A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and arc connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and arc electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, arc in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.

Abstract: The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements.

Abstract: The invention relates to an electrical distribution system (1), having a housing (3), in which fastening rails (13) are provided, which provide fastening points (15), which are arranged in lines, for the fastening of electrical components (17). Additionally, one or more, in particular explosion-protected, line-shaped heating elements (19) are provided in the housing (3), which heating elements each comprise a radiator body (23). The one or more heating elements (19) are each arranged below an associated group of fastening points (15), where electric current can be applied to the heating elements in order to heat electrical components (17) fastened at the associated fastening points (15).
