Abstract

The device for returning an armature (22), which can move along its longitudinal axis (L) into a coil (20), into an electromagnetic trip device (18), particularly a circuit breaker, comprises a leaf spring (40), held at one end, a lateral web (50), supporting the spring in the direction of the switch-off movement of the armature (22), and a slot (42), which is cut out of the circumference of the armature and to which the leaf spring engages in a positively locking manner at the other end. The leaf spring (40) is designed as an adjustable spring pack which can be held in the peripheral region of the magnetic trip device. This pack consists of at least two, preferably three, leaf-shaped spring elements (52, 54, 56) with the same and/or a different tension force. <IMAGE>
