The generator circuit breaker including a means of synchronization ensuring separation of the main contacts (5, 6) before the separation of the arcing contacts (15D, 15G) is distinguished by a lever (171) which is articulated at one end to a fixed contact part (4), and which, on the one hand, is linked on moving with the mobile main contact (6), and on the other hand, linked on moving with the mobile arcing contact (15D) by means of a spring (19), and with a ramp (21) having two horizontal levels (21A, 21C) linked one with the other by an inclined intermediary part (21B), the ramp acting as slide support for a trigger (23) which prevents or permits movement of the mobile arcing contact (15D). This arrangement permits the simple and unique mechanical synchronization of the mobile contacts.

Le disjoncteur de générateur comprenant un moyen de synchronisation assurant la séparation des contacts principaux (5,6) avant la séparation des contacts d'arc (15D,15G) est caractérise par un levier (171) qui est articulé par une de ses extrémités à une pièce de contact fixe (4), et qui est, d'une part, lié en déplacement avec le contact principal mobile (6), et d'autre part, lié en déplacement. avec le contact d'arc mobile (15D) par l'intermédiaire d'un ressort (19), et avec une rampe (21) présentant deux niveaux horizontaux (21A,21C) reliés entre eux par une partie intermédiaire inclinée (21B), la rampe servant de support de coulissement a un organe de déclenchement (23) qui bloque ou autorise le déplacement du contact d'arc mobile (15D). Cet agencement permet une synchronisation mécanique simple et unique des contacts mobiles.
