Abstract (en)
[origin: EP0793248A2] A safety fuse, in particular for armoured resistance elements, characterised by comprising: a bush (1) of dielectric material, internally housing two terminals (2,10) separated from each other and engagable by electrical conductors (16,15) of the resistance element (14), one (15) of said terminals being rigid with a metal block (11) retaining a metal slider (6) which is also in contact with the other terminal (16), elastic means (12) being provided which, following fusion of the metal block (11) by overheating, cause the slider (6) to move axially, with relative interruption of the electrical circuit. <IMAGE>
