Abstract

Fusible à indicateur de fusion 43 comportant un couvercle translucide 44, un élément fusible 54 et des éléments de circuit additionnels 52 et 56. Il est prévu un indicateur de fusion comprenant une diode luminescente 58 et un équipement formant résistance 60 qui sont connectés aux éléments de circuit additionnels en parallèle avec l'élément fusible, une paroi thermiquement isolante 66 étant en outre prévue dans le couvercle pour protéger la diode contre la chaleur de fusion de l'élément fusible. L'invention est applicable tant à des cartouches fusibles qu'à des fusibles du type bouchon fileté.Melting indicator fuse 43 having a translucent cover 44, a fuse element 54 and additional circuit elements 52 and 56. There is provided a melting indicator comprising a light emitting diode 58 and resistor equipment 60 which are connected to the circuit elements. Additional circuits in parallel with the fuse element, a thermally insulating wall 66 being further provided in the cover to protect the diode against the heat of fusion of the fuse element. The invention is applicable both to fuse cartridges and to threaded plug type fuses.
