Abstract
Dispositif de cartouche à fusibles pour fortes intensités. Il comprend quatre corps isolants tubulaires 2 à section carrée, disposés très près les uns des autres entre deux têtes communes 3 et 4, l'une comportant des bossages auxquels sont soudés les éléments fusibles, tandis que l'autre est percée d'alésages épaulés pour la soudure des autres extrémités de ceux-ci, ces alésages étant fermés par des bouchons ou des couvercles. Il peut être prévu des colonnettes intérieures de refroidissement. Application notamment aux cartouches montées sur des barres omnibus telles que 1 pour porter directement un appareil 10.
