Abstract
The present disclosure relates to an arc extinguishing chamber of an electrical circuit breaker, including an arc-forming chamber enclosing a fixed contact and a moving contact, which, at the time of their separation, form an arc between them, said forming chamber communicating with the input of an arc-quenching chamber comprising a stack of separators extending parallel to one another, and including a magnetic release situated on the side of the fixed and moving contacts and a switching horn situated on the opposite side, where the form of the separators varies progressively from one separator to the next, or by groups of identical separators from one group to another, or a mixture of both, in such a way that this form changes from the V having the largest opening surface area to the V having the smallest opening surface area, in the direction from the magnetic release to the switching horn.
