An electric arc breaker device comprises a contact zone in which there are present at least one stationary contact and at least one movable contact that is movable relative to the stationary contact. The contacts are capable of being put into contact with each other and of being separated from each other. An arcing horn is present facing the stationary contact, the height hc of the arcing horn being greater than or equal to the height ht of the stationary contact, and the arcing horn presenting a folded-back arc switching portion extending in a direction away from the stationary contact.
