Electric arc-control device

An electric arc breaker device comprising:

• 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 being capable of being put into contact with each other and of being separated from each other;
• and
• an arcing horn present facing the stationary contact, a height hc of the arcing horn being greater than or equal to a 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;
• the device being present in a box and the arcing horn having a width L equal to an inside width of said box,
• wherein the arcing horn comprises a first portion facing the stationary contact extending from a first end located beside a stationary support to a second end forming a bend of the arcing horn, said bend being present at a height greater than the height ht, of the stationary contact, and
• wherein the arcing horn further comprises a second portion forming the folded-back arc switching portion which extends from the second end and which is superposed to a material of the first portion, and
• wherein a width of the first portion varies to reach a maximum value between the first end and the second end.
