Abstract (en)

1. A circuit breaker of the type comprising, in a housing (10), a first contact (20A) which is fixed, a second contact (20B) which is mounted movably between a closed position and a tripped position and which is urged towards said tripped position by an opening spring (29), a closing and tripping actuating member (37) which is mounted movably between a closing position and a tripping position and which is urged towards said tripping position by a return spring (42), a locking mechanism (43) which is disposed between the opening and tripping actuating member (37) and the housing (10) and which is capable of releasably holding said closing and tripping actuating member (37) in the closing position, a latching mechanism which is disposed between the closing and tripping actuating member (37) and the movable contact (20B) and which comprises two latching members (32, 74) capable of releasably engaging with each other to hold the movable contact (20B) in the closed position, and at least one tripping member which is capable of causing disengagement from each other of said latching members (32, 74) whereby the movable contact (20B) is freed to move from its closed position to its tripped position, characterized in that one (32) of the latching members of the latching mechanism is an integral part of the opening spring (29) of the movable contact (20B).

Abstract (fr)

Il s'agit d'un disjoncteur dans lequel, entre la manette d'enclenchement et de déclenchement (37) et le contact mobile (20B), est établi un mécanisme d'accrochage comportant deux organes d'accrochage susceptibles de venir en prise de manière débrayable l'un avec l'autre pour maintien de l'ensemble en position d'enclenchement. Suivant l'invention, l'un de ces organes d'accrochage fait partie intégrante du ressort d'ouverture (29) associé au contact mobile (20B) et est constitué par la branche d'extrémité libre (32) de ce ressort. Application aux disjoncteurs.
