Abstract

A fuse cartridge for example of the cylindrical type comprising an insulating cylindrical body ending in two conducting end pieces and a fuse element connected electrically to the end pieces, further comprising two pistons housed in the body which are movable in translation in opposite directions to each other and collect the gases released by the electric arc at the time of its appearance, so that the pressure of the gases exerts on each piston a force which causes it to move towards a position in which the arc is totally sheared.
