Abstract (en)
[origin: WO2015063120A1] In an arc quenching chamber insert (1) for an electrical switching device (2), in which the arc quenching chamber insert (1) comprises a metal plate holder (3) made of an insulating material, and in which a predefinable plurality of metal plates (4) are mounted in the metal plate holder (3) in a predefinable spaced relation to each other, it is proposed that a first end region (5) of the metal plate holder (3) be designed with predefinable contouring, and that a second end region (6) of the metal plate holder (3) at the opposite end from the first end region (5) have mirror-inverted contouring compared with the first end region (5).
