Abstract: The invention relates to a nozzle (20) with an electric arc-blast comprising of a median part (27) made of a first dielectric material and two end parts (9, 11). The nozzle (20) comprises an insert (22) made of a second dielectric material, separate from the first dielectric material and chosen from among: a composite material obtained from a second composition comprising a fluorocarbon polymer matrix and at least one inorganic filler A chosen from among a sulfur, a ceramic and an oxide chosen from among SiO 2 , TiO 2 , Al 2 CoO 4 , ZnO, BaTiO 3 and P 2 O 5 , in a percentage weight ranging between 0.1 % and 10 %, with respect to the total weight of the second composition, and/or at least one inorganic filler B chosen from among a graphite, a mica, a glass and a fluoride, in a percentage weight ranging between 5 % and 50 %, with respect to the total weight of the second composition, and a ceramic material obtained from a third composition comprising at least one compound chosen from among a carbide, a boride and an oxide. The invention also relates to a circuit breaker comprising such a nozzle (20).
