Abstract

A low voltage circuit breaker (1) comprising a case which contains at least one fixed contact (2) electrically connected to a terminal which is suitable for connection with an electric circuit (3), a movable conductive arm (4) provided with at least one contact piece (5), and actuating means (10) which are operatively connected to the movable conductive arm (4) and supply the energy for moving it, characterized in that said actuating means (10) comprise a piezoelectric motor (11) which is mechanically linked to said movable conductive arm (4); and a command and control unit (30) which, following an intervention command, drives said piezoelectric motor (11) so that it actuates the movable conductive arm (4) and allows clcctrical coupling/uncoupling of said contact piece (5) with respect to said fixed contact (2). <IMAGE>
