Removable electric current switching element and electrical switchgear for switching an electric current comprising such a removable switching element

A removable electric current switching element, comprising:

• a housing provided with a first bottom plate and a second bottom plate which are opposite one another;
• fixed electrical contacts, which are rigidly connected to the first bottom plate;
• electrically mobile contacts movable with respect to the fixed electrical contacts, said mobile contacts being borne by a movable contact holder movable in translation with respect to the second bottom plate;
• the housing comprising insulating walls which extend around the electrically mobile contacts from the second bottom plate and along a direction perpendicular to the second bottom plate;
• wherein the housing further includes protection walls which at least partially cover inner faces of the insulating walls, said protection walls being formed as a single piece with the second bottom plate, and
• wherein the protection walls include folded-over edges which surround the ends of the insulating walls along the direction perpendicular to the second bottom plate such that the protection wall at least partially covers the inner faces of the insulating walls and covers a portion of outer faces of the insulating walls.
