摘要：A circuit arrangement (1) for current limiting, which has a main current path (2)with at least one contact point (3) having an arc extinguishing region (4) from which abranch (7) is led away to an external connection (8). The branch (7) is connected, via acontact means (6), in the region which is filled with electrically conductive arc plasmawhen the contact gap is opened. The gaps between in each case one contact of thecontact point (3) and the contact means (6) determined the voltage on the input side andon the output side during switching off. The contact point (3), or the contact points, ofthe main current path (2) is/are bridged by a parallel branch (15) having a further contactpoint (16), delayed trip devices (18) and a current-limiting resistor (17), a contact of thefurther contact point (16) being controlled by the delayed trip device (18). The outputside is decoupled from the input side, on the output side, current and voltage intrusionsfor load branches during switching off being prevented.
