Abstract

A kinematic system for actuating the movable contact of automatic electric breakers includes an actuation mechanism (5) which includes an external handle (9) which is pivoted to the body (3) of a breaker and is connected to the cross-member (13), which is in turn connected to an actuation lever (15) which is operatively associated with a reset spring (17) and with an actuation spring (19), both of which are coupled to a common pivot (21); a mushroom-shaped member (23) of a relay of the breaker acts on a reset lever (25) which is in turn kinematically associated with a hook (27) supported by a second common pivot (29); an engagement lever (31), retained by the hook, is suitable to act on the rear part of a traction lever (33).
