Abstract

An electric arc extinction chamber comprises a stack of electric arc splitter plates. The splitter plates define an inlet of the extinction chamber that is to be present facing electric contacts, and a back of the extinction chamber. At least one permanent magnet is present inside the extinction chamber in a central zone in the width direction of the extinction chamber and beside the back thereof. The magnet presents magnetization having a non-zero component along an axis extending between the inlet and the back of the extinction chamber.
