Abstract
A circuit breaker comprising a first permanent current contact and a first arcing contact that are fixed, a second permanent current contact and a second arcing contact that are movable in a longitudinal direction to be connected with or separated from the fixed contacts, and a mechanism for displacing the moving contacts in the longitudinal direction in such a manner so as to separate the permanent current contacts before separating the arcing contacts. The mechanism includes a shaft movable in the longitudinal direction and secured to the moving permanent current contact, and a crank piece having two limbs forming an L-shape and rotatable about an axis that is fixed relative to the longitudinal direction and that extends perpendicularly to the direction, one limb of the crank piece being connected to the moving arcing contact, and its other limb being connected to the shaft.
