<p>A kinematic mechanism for a low-voltage protection and/or current interruption device, comprising actuation means that are operatively associated with moving contact means that can be coupled/uncoupled with respect to corresponding fixed contact means, the moving contact means comprising at least one moving contact and the fixed contact means comprising at least one fixed contact, the actuation means comprising means (11) for actuating and releasing the moving contact which are operatively connected to an actuation arm by virtue of connection means, its particularity consisting of the fact that the means for the actuation and release of the moving contact comprise a single body (11) that has a first portion (12), which is operatively associated with the moving contact means and with the connection means, and a second portion (13), which is operatively associated with the connection means, the first and second portions being arranged coaxially on a common rotation axis (20) and being connected by virtue of a third portion (15) that comprises at least one first elastic and resilient element and allows a mutual rotation of the first and second portions with respect to the common rotation axis.</p> |
