Abstract

L'invention concerne un dispositif de protection contre la surintensité de courant destiné à être utilisé dans des appareils de protection contre la surtension avec un déclencheur mécanique supplémentaire, de préférence conçu comme percuteur. Selon l'invention, une première unité fonctionnelle contenant le déclencheur mécanique comporte un premier élément fusible. Une seconde unité fonctionnelle, conçue comme protection contre la surcharge, possède un second élément fusible. Chaque unité fonctionnelle est agencée dans un boîtier, des capots de recouvrement opposés, latéraux étant situés sur le boîtier respectif et les conducteurs fusibles se trouvant respectivement à l'intérieur du boîtier et étant raccordés électriquement aux capots de recouvrement. La première et la seconde unité fonctionnelle sont montées en parallèle électriquement, ce montage en parallèle étant monté en série avec l'appareil de protection contre la surtension. Les unités fonctionnelles forment un ensemble mécanique commun, chaque boîtier étant entouré d'une enveloppe séparée ou les deux boîtiers étant entourés d'une enveloppe élastique commune ou d'un autre boîtier, toutefois élastique.
