Abstract

L’invention concerne un dispositif de protection (1) contre les surtensions comportant :- au moins une première borne de connexion (13, 47) et une deuxième borne de connexion (14); - un premier ensemble de composants de protection comprenant au moins une première varistance (6) et un éclateur à gaz (8), qui sont reliés l’un à l’autre par une liaison thermofusible (21) ; - au moins un premier dispositif coupe-arc qui comporte un volet isolant (26) qui est configuré pour se déplacer, lors d’un passage de la liaison thermofusible (21) d’un état connecté vers un ’état déconnecté ; le premier ensemble de composants de protection comporte une tresse souple (23) qui est soudée à l’éclateur à gaz et raccordée électriquement à une pièce de connexion (22) elle-même raccordée électriquement à la deuxième borne de connexion (14), ladite tresse souple (23) étant apte à se déformer afin de permettre à l’éclateur à gaz (8) de s’éloigner de la première varistance (6).
