Abstract

La présente invention a trait à un dispositif limiteur de courant muni de dispositifs de décompression sensibles pour la réduction de pressions internes lors du fonctionnement du limiteur de courant. Dans un agencement spécifique, le dispositif de décompression comprend un passage qui s'ouvre lors du fonctionnement du limiteur de courant pour établir une communication entre l'intérieur et l'extérieur du limiteur de courant. Le passage comporte en son sein un matériau fusible qui se fond par le réchauffement au sein du limiteur de courant dans des conditions prédéterminées de faute de courant élevé. Dans un agencement spécifique, le passage est formé à travers une borne de contact du limiteur de courant. Dans un agencement, le dispositif limiteur de courant comporte une section d'échappement adjacente et la borne de contact s'étend dans la section d'échappement adjacente.
