Abstract
The present invention relates to an arc chamber to extinguish electric arcs for a contactor with an extinguishing system, a blowing device which blows electric arcs into the extinguishing system, and a plurality of lamellar electric arc extinguishing elements between which flow channels are formed, wherein the flow channels each have a scattering section and wherein the scattering sections of adjacent flow channels are formed with different inclinations so that the blown air is deflected into different directions by the flow channels. The invention further relates to a contactor with such an arc chamber.
