Abstract

Disjoncteur multipolaire à boîtier isolant partagé par une cloison 44 médiane en deux compartiments supérieur 46 et inférieur 48 superposés. Le compartiment supérieur 46 accessible de la face avant après enlèvement du couvercle 16 sert de logement au mécanisme d'actionnement 22 doté d'une manette 20 de commande et d'un crochet de déclenchement 84, au barreau 56 support des bras de contact, et à une pluralité de blocs auxiliaires de commande 50, 54, coopérant avec le mécanisme 22. Application : protection des réseaux BT.Multipolar circuit breaker with insulating box shared by a middle partition 44 into two superimposed upper 46 and lower 48 compartments. The upper compartment 46 accessible from the front face after removal of the cover 16 serves as a housing for the actuating mechanism 22 provided with a control lever 20 and a triggering hook 84, for the bar 56 supporting the contact arms, and to a plurality of auxiliary control units 50, 54, cooperating with the mechanism 22. Application: protection of LV networks.
