Abstract

Thermo-rupteur comprenant un élément de commutation dans lequel circule le courant, qui est destiné à déclencher la coupure et qui est réalisé en alliage à mémoire de forme et à effet bidirectionnel. Il comprend au moins un dispositif exerçant une contrainte, par exemple un dispositif tendeur 16 et/ou un dispositif de compression 18, qui coopère avec cet élément de commutation 11 et dont la force qu'il exerce sur ce dernier par l'intermédiaire d'une lame de contact 12 permet de fixer la température de la coupure. Application aux disjoncteurs assumant la fonction double de coupure en cas de surintensité et en cas de courant de court-circuit.
