Abstract (en)
[origin: EP1045416A2] A plate (14) is situated on free sides of a U shaped yoke of a magnet (11) for the release of the plate (14) of an armature connected with the magnetic core (41). With occurrence of an overcurrent the disk armature pulls against the plate and releases switching lock. In case of short-circuit current, the magnetic armature (20) opens due to a strike of a pin (30) onto a contact location (33).
