Abstract

Die Erfindung betrifft eine Kontaktanordnung für strombegrenzende Schutzschalter im Niederspannungsbereich, insbesondere für strombegrenzende Leistungsschalter. Eine Drehkontaktbrücke (10) ist über vier paarweise symmetrisch zu beiden Seiten der Kontaktbrücke (10) angeordnete Kontaktkraft-Zugfedern (18) mit einer Schaltwelle (6) verbunden. Zur Rückfallverzögerung der von feststehenden Kontakten (16) elektrodynamisch abgestoßenen Kontaktbrücke (10) wirken Verbindungsstücke (20) zwischen den ersten Enden (19) des jeweils einen Zugfederpaares gegen Verlängerungen (28) an den zweiten Enden (21) des jeweils anderen Zugfederpaares.

The invention relates to a contact arrangement for current-limiting circuit breakers in the low-voltage range, in particular for current-limiting circuit breakers. A rotary contact bridge (10) is connected to a selector shaft (6) by way of four contact-force tension springs (18) arranged in pairs symmetrically on both sides of the contact bridge (10). To delay the decay of the fixed contacts (16) electrodynamically repelled contact bridge (10) connecting pieces (20) between the first ends (19) of each one Zugfederpaares against extensions (28) at the second ends (21) of the other pair of tension springs.
