Abstract

Die Erfindung betrifft ein Leistungsschalter für hohe Ströme und Niederspannung, der ein Unterteil (2) mit Zwischenwänden (5), einen in Seitenblenden (28) gelagerten Betätigungsmechanismus (30) mit einem Kniehebelsystem (34) aufweist und mehrere Kontakteinheiten (9 ... 11) aufweist. Die Kontakteinheiten (9 ... 11) enthalten mehrere bewegliche Kontaktfingern (18), die in einem U-förmigen Kontakthalter (24) gegen die Wirkung von Kontaktdruckfedern (26) schwenkbar gelagert sind. Ein Verbindungssteg (38) aus isolierendem Formstoff ist einstückig mit den Kontakthaltern (24) verbunden und verläuft oberhalb der Kontaktdruckfedern (26). Ein mit der mittleren Kontakteinheit (10) starr verbundenes Halteblech (42) ist gelenkig mit dem Kniehebelsystem (34) verbunden und in den Seitenblenden (28) schwenkbar gelagert. Mit den Kontaktfingern (18) verbundene flexible Verbindungsleiter (17) sind in Flucht zur Schwenkachse (51) des Haltebleches (42) an zugehörige Stromschienen (13) geführt.

The invention relates to a circuit breaker for high currents and low voltage, comprising a lower part (2) with intermediate walls (5), an actuating mechanism (30) mounted in side panels (28) with a toggle system (34) and a plurality of contact units (9 ... 11 ) having. The contact units (9 ... 11) comprise a plurality of movable contact fingers (18) which are pivotally mounted in a U-shaped contact holder (24) against the action of contact pressure springs (26). A connecting web (38) of insulating molding material is integrally connected to the contact holders (24) and extends above the contact pressure springs (26). A holding plate (42) rigidly connected to the central contact unit (10) is pivotally connected to the toggle lever system (34) and pivotally mounted in the side panels (28). Flexible connecting conductors (17) connected to the contact fingers (18) are guided in alignment with the pivot axis (51) of the retaining plate (42) to associated busbars (13).
