Definitions
- an object of the present invention is to provide an automatic low-voltage circuit breaker in which the kinematic chain of the circuit breaker is provided by means of a structure that is simplified with respect to the known art and with a reduced number of components while maintaining the functional performance unchanged.
- said lever is a lever for actuating and supporting the moving contact 3, which is pivoted on a pivot that is rigidly coupled to the enclosure 2 and also has a single body that comprises a first rigid portion 5', on which the moving contact 3 is mounted and which is functionally associated with the arm 9 by means of a connecting element 7, generally a U-shaped member that can slide in a seat 18; a second rigid portion 6', which is suitable to interact functionally with a release device 20 of the circuit breaker, for example a relay, and has a hook- shaped end 19 that interacts with the U-shaped member 7 so as to engage it and couple its own movement to the movement of the portion 5' when necessary; and at least one first flexible hinge for mutually connecting the two rigid portions 5' and 6'.
- the lever 56 can comprise a second flexible hinge suitable to connect the first rigid portion 5' to the enclosure 2 so as to allow movement with respect to it; as shown in Figure 4, the second hinge is constituted by an elastic and resilient metallic lamina or insert 16, which is embedded at one end in the first rigid portion 5' and is arranged at the other end so as to react on the inner face of the enclosure 2, for example against a suitable protrusion, not shown.
- the spring 12 used in the known art is no longer present, since its function is integrated in the body of the lever 56; accordingly, the corresponding positioning, setting and assembly operations are avoided.
