Abstract

Abstract Translated from French L'invention est relative à un disjoncteur multipolaire formé par l'assemblage modulaire d'un bloc de coupure et d'un bloc déclencheur magnétothermique interchangeable en fonction du calibre souhaité Le shunt (64, 66) souple du bras de contact (30) mobile de chaque pôle est solidarisé directement à la plage de liaison (52R) comportant une face de contact (62) coopérant avec la plage de connexion (50R) du block déclencheur (44), et, une face opposée (60) dotée d'un écrou (58). Chaque plage de liaison est positionnée à jeu vertical dans une rainure du boîtier (12) du block de coupure. La palette mobile (92) du déclencheur électromagnétique est associée à un ressort de traction ancré au barreau de réglage de l'entrefer. Application: disjoncteurs de protection pour réseaux à basse tension. The invention relates to a multipole circuit breaker formed by the modular assembly of a cut-off block and a thermothermal tripping block interchangeable according to the desired rating The flexible shunt (64, 66) of the movable contact arm (30) of each pole is secured directly to the connection pad (52R) comprising a contact face (62) cooperating with the connection pad (50R) of the trigger block (44), and, an opposite face (60) provided with a nut (58). Each connection pad is positioned vertically in a groove in the housing (12) of the cut-off block. The movable pallet (92) of the electromagnetic trip device is associated with a tension spring anchored to the air gap adjustment bar. Application: protective circuit breakers for low voltage networks.
