description A system for switching gases appearing after a short-circuit switching procedure in electrical service devices, particularly in low-voltage power switches, includes a switching gas cooling assembly and particle capture arrangement. Downstream of the flow path of switching gases issuing from at least one switching chamber outlet window, the switching gas cooling assembly is arranged in a blow-out chamber. In the space behind the at least one switching chamber outlet window and prior to entry of the switching gases into the switching gas cooling assembly, there is arranged a flow element around which the switching gases can flow and which has a cross section which corresponds to or is greater than the cross section of the switching chamber outlet window. The flow elements act as the particle capture arrangement and thus as a protection device for the switching gas cooling arrangement.
