Abstract: A low-voltage circuit breaker includes: at least one external conductor section from an external conductor power terminal of the low-voltage circuit breaker to an external conductor load terminal of the low-voltage circuit breaker; a neutral conductor section from a neutral conductor terminal of the low-voltage circuit breaker to a neutral conductor load terminal of the low-voltage circuit breaker; a mechanical bypass switch arranged in the external conductor section; a semiconductor circuit arrangement switched in parallel to the bypass switch; an electronic control unit; and a first current measuring arrangement arranged in the external conductor section, the first current measuring arrangement including a first shunt, which is connected to the electronic control unit. The electronic control unit actuates the mechanical bypass switch and the semiconductor circuit arrangement upon detecting a prespecifiable overcurrent that includes a short circuit current, by the current measuring arrangement.

Abstract: A relay includes an electromagnetic drive unit with a rotatable armature and a yoke. The rotatable armature includes a first magnetic contact region and the yoke includes a second magnetic contact region. The first magnetic contact region is in touch with the second magnetic contact region in a first state of the relay. The relay further includes at least one immovable first electric contact and a moveable contact arm with at least one second electric contact. The first electric contact contacts the second electric contact in the first state. The rotatable armature and the moveable contact arm are positioned together on a shaft and the shaft is embodied as a torsional element.
