[0025] FIG. 1 illustrates an exhaust gas module 100 according to the invention for an electrical switch 1000. The electrical switch 1000 has outlets for switching gases on its output side 1010 and/or on its input side 1020. In the illustration of FIG. 1, the exhaust gas module 100 is mounted on an electrical switch 1000 such that the switching gases are directed into an exhaust gas channel 150 of the exhaust gas module 100.

[0026] The exhaust gas channel 150 deflects the switching gases substantially at a right angle and can interact in modular fashion with a neighboring exhaust gas channel 150 of a neighboring exhaust gas module 101 in order to bring together the deflected switching gases. This will be explained in more detail with reference to FIGS. 4A and 4B, 5, 6A and 6B, 7 and 8.

[0027] The exhaust gas module 100 according to the invention is fastened to a wall 2000 of a switch cabinet. The switching gases which have been brought together can be led out of the switch cabinet via a flexible channel 222.

[0028] FIG. 2 shows, in a sectional illustration, the exhaust gas module 100 according to the invention mounted on the electrical switch 1000. The wall 2000 of the switch cabinet and the flexible channel 222 which leads the switching gases which have been brought together out of the switch cabinet are also illustrated.

[0029] FIGS. 3A and 3B show the exhaust gas module 100 according to the invention mounted on the wall 2000 of the switch cabinet and with a flexible channel 222 from different sides.

[0030] In the case of the exhaust gas module 100 according to the invention, an exhaust gas channel 150 is arranged on the output side 1010 or on the input side 1020 of the electrical switch 1000; it is also possible for the exhaust gas module to comprise an exhaust gas channel 150 on the output side 1010 and on the input side 1020 of the electrical switch.

[0031] FIGS. 4A and 4B illustrate a device formed by two exhaust gas modules 100, 101 according to the invention. The exhaust gas channel 150 deflects the switching gases substantially at a right angle and the exhaust gas channel 150 interacts in modular fashion with a neighboring exhaust gas channel 151 of a neighboring exhaust gas module 101 in order to bring together the deflected switching gases.

[0032] The exhaust gas channel 150 comprises ribs 171, 172 which isolate the switching gases from one another pole by pole. Similarly, barriers 161, 162, 163, 164 can be arranged at the exhaust gas channel 150, said barriers being able to isolate electrical lines 191, 192, 193 from one another in the event of the exhaust gas module 100 being mounted on the electrical switch 1000.

[0033] According to the illustration of FIGS. 4A and 4B, the barriers 161, 162, 163, 164 can be arranged in a plane directly above or below the exhaust gas channel 150.

[0034] The device according to the invention therefore comprises a first exhaust gas module 100 and a second exhaust gas module 101, wherein the first exhaust gas module 100 is mounted adjacent to the second exhaust gas module 101 such that the respective exhaust gas channels 150, 151 grip one inside the other in modular fashion and the deflected switching gases are thereby brought together. According to the illustration of FIGS. 4A and 4B, an electrical switch 1000 is mounted on the first exhaust gas module 100 and a second electrical switch 1001 is mounted on the second exhaust gas module 101.

[0035] The first electrical switch 1000 can be a circuit breaker; similarly, the second electrical switch 1001 can likewise be a circuit breaker.

[0036] FIG. 5 shows in more detail the device according to the invention formed by a first exhaust gas module 100 and second exhaust gas module 101. The respective exhaust gas channels 150, 151 grip one inside the other in modular fashion, as a result of which the deflected switching gases are brought together.

[0037] FIG. 6A likewise illustrates the device according to the invention formed by a first exhaust gas module 100 and second exhaust gas module 101 and, mounted on said exhaust gas modules, the first electrical switch 1000 and the second electrical switch 1001. FIG. 6B illustrates the first exhaust gas module 100 with a first exhaust gas channel 150 and the second exhaust gas module 101 with a second exhaust gas channel 151. Furthermore, coverings 600, 601 are shown which close the respective exhaust gas channels 150, 151 and therefore ensure that the exhaust gas modules 100, 101 withstand the turning-off pressure of the electrical switches 1000, 1001 and that as little gas as possible passes to the outside or to the neighboring pole due to leakages of the exhaust gas channels 150, 151.

[0038] FIG. 7 shows the device according to the invention formed by a first exhaust gas module 100 and second exhaust gas module 101. Barriers 161, 162, 163, 164 are arranged here at the exhaust gas channel 150, said barriers isolating electrical lines 191, 192, 193, such as busbars, from one another when the electrical switch 1000 is mounted.

[0039] FIG. 8 shows the underside of the illustration of the device according to the invention from FIG. 7. The respective exhaust gas channels 150, 151 of the first exhaust gas module 100 and of the second exhaust gas module 101 grip one inside the other in modular fashion, as a result of which the deflected switching gases are brought together.

[0040] The modular exhaust gas modules 100, 101 with exhaust gas channels 150, 151 are shaped in such a manner that the exhaust gases or switching gases thereof can flow into the neighboring channel and are therefore conducted from one exhaust gas module into the next exhaust gas module until they are conducted out of a switch cabinet at any location at the end. This ensures that, after a short-circuit of the electrical switch, the resulting soot and contact combustion particles are guided in a defined manner out of a switch cabinet and, as a result, the switch cabinet is not soiled and therefore also does not have to be cleaned.
