ARC QUENCHING CHAMBER INSERT

摘要

An arc quenching chamber insert for an electrical switching device has a metal plate holder made of an insulating material, and in which a predefinable plurality of metal plates are mounted in the metal plate holder in a predefinable spaced relation to each other. A first end region of the metal plate holder is designed with predefinable contouring, and that a second end region of the metal plate holder at the opposite end from the first end region have mirror-inverted contouring compared with the first end region.
