Abstract (en)
[origin: WO2011114045A1] Electric circuit breaker forming a breaker switch in particular, in which a conducting blade is broken by the tripping of a pyrotechnic activation gas generator. According to the invention, a gas generator (15) with pyrotechnic actuation is designed so as to emit gases resulting from the combustion of a charge, and the generator is associated with a variable-configuration chamber (17) and a breakable conducting blade (19) constitutes a back wall of this chamber, the breaking of the blade under the actuation of the gases causing the interruption of the electric circuit of which the blade forms part.
