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.

Abstract: A low-voltage circuit breaker comprising one or more electrical poles, each of said poles having an internal space with a contact area and an arc extinguishing area, a fixed contact assembly and a movable contact assembly being positioned in said contact area, said movable contact assembly being movable between a closed position in which it is into contact with said fixed contact assembly and an open position in which it is spaced apart from said fixed contact assembly, an arc chamber comprising a plurality of substantially parallel arc-breaking plates made of a ferromagnetic material being positioned in said arc extinguishing area. The low-voltage circuit breaker is characterized in that said arc chamber further comprises at least one arc-breaking plate which is at least partially made of a ceramic material.
