Abstract

A double-pole circuit breaker (1) for enclosed boxes of civil range electric equipment has longer life and comprises, within a body (8), neutral (15) and protected (14) poles, moving (23,19) and fixed (22,18) contacts for each pole (15, 14), a diaphragm (3) in said body (8), two chambers (34,33) formed in said body (8) on opposed sides of the diaphragm (3) and being each adapted to accommodate a respective one of said moving contacts (23,19) for movement therein through a preset path (T) toward and away from a respective one of the fixed contacts (22,18), a throughgoing socket (35) in said diaphragm (3), and a metal crosspiece (37) having a middle portion inserted in said socket (35) and end portions (39,38) overhanging in said chambers (34,33) at a location facing said path (T).
