Abstract: A device for monitoring a current in a primary conductor with respect to a predetermined current threshold, comprising: a magnetic circuit associable to the primary conductor and comprising a fixed part and an element which can rotate about a rotation axis; at least one spring operatively connected to the rotating element for keeping it in a first position, the spring being elastically deformable along a linear axis; and sensing means operatively associated to the magnetic circuit. The magnetic circuit is configured in such a way that the rotating element rotates from the first position to a second position when the current in the primary conductor exceeds the predetermined current threshold, so as to at least reduce one or more air gaps between the rotating element and the fixed part and to elongate the spring from a first length to a second length. The sensing means are configured for generating an output electrical signal caused by the rotation of the rotating element from the first position to the second position.The at least one spring is operatively connected to the rotating element in such a way to tilt towards the rotation axis moving above a surface of the rotating element which is transversal to the rotation axis, during the rotation of the rotating element from the first position to the second position.

Abstract: The present invention relates to a control mechanism for the displacement of at least one moving contact of a low-voltage circuit-breaking device. The control mechanism comprises elastic means operatively connectable to the moving contact, at least a first element of which is operatively connected to a second element by means of pin-shaped connection means. The first and second elements each comprise a pair of facing lateral portions that are connected by a transverse portion. The pin-shaped connection means comprise a pair of pin-shaped ends, each of which emerges from one side of a lateral portion of the first element. Said pin-shaped means also comprise a pair of seats, each of which is defined on a lateral portion of the second element. Each pin-shaped end is inserted in a corresponding seat so as to configure an axis of mutual rotation between the first and the second elements. The elastic means are arranged so as to exert a retaining force on the pin-shaped ends sufficient to keep them coupled to the corresponding seats in which they are inserted.
