A circuit breaker comprises a pair of separable contacts arranged in an opening volume. A plurality of flat de-ionization fins are arranged inside an arc extinguishing chamber opening out onto the opening volume. The chamber is bounded by two opposite side walls, a rear wall located away from the opening volume, a bottom wall and a top wall. Each fin has a free attack edge exposed to the arc. The free edges of the fins laterally bound a longitudinal gulley extending in a heightwise direction from the bottom electrode to the top wall, and longitudinally from a first longitudinal end opening out onto the opening volume at a second longitudinal end tapering to form a stack near to the rear wall, passing via a narrow intermediate portion. A bottom longitudinal electrode partially covers the bottom wall and extends longitudinally facing the gulley at least from the second contact up to the stack.
