A kinematic device for actuating the moving contact, particularly for automatic electric breakers, includes inside a box-like body, a motion lever (2) which is connected to a lever (10) for actuating the breaker and is pivoted to the box-like body by means of a first pivot (3). The motion lever (2) is articulated to linkages (11) which are pivoted, at the other end, to the first end (12) of a cross-member (13) which is operatively associated with a moving contact (15). The first end (12) of the cross-member (13) slidingly engages an engagement lever (21) which is pivoted to the box-like body by means of a second pivot (22) and is provided with a locking arm (30) of a control part (31) which is pivoted to the box-like body by means of a third pivot (32). The third pivot (32) constitutes the fulcrum of the moving contact (15). |
