Abstract: An electrical arc absorber system (100) for a switchgear, controlling a current, is described. The arc absorber system includes an impedance reduction system (110) for reducing the impedance of an electrical arc appearing in the switchgear between the current phases or the current phases and the ground. The impedance reduction system reduces the impedance for the electrical arc compared to the impedance of the electrical arc in the medium present in the switchgear. Further, the impedance reduction system (110) comprising at least one arc catcher (111; 112; 113) for the current phases of the current. Also, a switchgear including an arc absorber system and a method for operating a switchgear is described.
