Abstract Trip device of the suction or pull-in armature type, having a yoke (18; 35) supporting a fixed permanent magnet (22) and a movable elongated armature (23) having a head member (25). The armature (23) and the yoke (18; 35) forming a first magnetic circuit for holding the armature (23) in a first position with the permanent magnet (22), in which first position the head member (25) protrudes outside the yoke (18; 35). For moving the armature (23) electromag- netically and/or electrothermally to a second position in which the head member (25) protrudes further outside the yoke (18; 35), the yoke (18; 35) is provided with electrothermal bimetal means (33; 37). For moving the armature (23) to the second position independently of the polarity of an electrical current, a second magnetic circuit is provided, consisting of a further yoke and one or more magnet windings (30), or consisting of a pair of mutually magnetically separate branches (44, 45; 50, 51) magnetically con- nected in series with the first magnetic circuit, and one or more magnet windings (46) for mutually oppositely magnetizing the branches (44, 45; 50, 51).
