An arc extinguishing chamber includes an arc formation chamber containing a stationary contact and a movable contact which form an arc between them when separated. The arc formation chamber communicates with an inlet of a second chamber. A separating wall is placed in a volume downstream from said second chamber. The wall extends in the direction of the gas flow to partition the volume in the direction of the flow of the gases and exhaust outlets enabling the quenching gases to be removed outside of the apparatus. The separating wall(s) extend(s) in such a way as to partition in the direction of the flow to the outlets and to thereby form at least a first removal duct and a second removal duct, said ducts each being associated with an exhaust outlet and enabling a substantially complete separation to be achieved between a first flow and a second flow.
