ABSTRACT:
In an arc contact system for electrical circuit breakers, in particular of the type using an arc extinguishing fluid, comprising a stationary contact and a movable contact, one of the two arc contacts is formed by a tubular cylindrical body bearing a hollow sleeve of arc resistant material at its end destined to cooperate with the other arc contact; and the other arc contact is formed by a substantial cylindrical rod provided with at least one central longitudinal cut, suitable to render elastically yielding in the radial direction said rod, destined to be inserted inside the tubular cylindrical body of said first arc contact.
