Abstract

L'invention fournit un fusible permettant d'interrompre de manière sûre une surintensité. Ce fusible (1) est équipé : d'un substrat isolant (10) ; d'un câblage (11) ; d'une partie métallique à bas point de fusion (20) ; et d'un corps générateur de chaleur (30). Le câblage (11) est placé sur une face principale (10a) du substrat isolant (10). La partie métallique à bas point de fusion (20) est agencée sur le câblage (11), possède un point de fusion plus bas que ce dernier, et une fois fondue, le dissout. Le corps générateur de chaleur (30) chauffe la partie métallique à bas point de fusion (20). Selon une vue en plan, le corps générateur de chaleur (30) est agencé d'un autre côté que celui d'une partie extrémité du câblage (11) dans sa direction de prolongement dans une région où la partie métallique à bas point de fusion (20) est placée.
