Eine Schaltkontaktanordnung dieser Art ist durch die DE 35 39 786 A1 bekanntgeworden. Die Lagerarme sind dabei Bestandteil eines Lagerbügels, der an einen Haltekörper für die Kontakthebel maßgerecht angepaßt ist. Während es sich hierbei um eine nur aus Metallteilen bestehende Konstruktion handelt, sind auch Schaltkontaktanordnungen bekannt, die aus einer Kombination von Kunststoff-Formteilen und Metallteilen zusammengesetzt sind. In jedem Fall sind diese Schaltkontaktanordnungen für eine bestimmte Anzahl von Kontakthebeln bemessen. Für eine mehrere Bemessungsströme umfassende Baureihe von Niederspannungs-Leistungsschaltern werden daher entsprechend viele unterschiedliche bewegbare Schaltkontaktanordnungen benötigt. Der Erfindung liegt die Aufgabe zugrunde, die Herstellungskosten für diese Vielzahl von Schaltkontaktanordnungen zu verringern.A switch contact arrangement of this type is through the DE 35 39 786 A1 has become known. The bearing arms are included Part of a bracket that is attached to a holding body for the contact lever is adjusted to size. While it is a construction consisting only of metal parts is also known, switch contact arrangements are known a combination of molded plastic parts and metal parts are composed. In any case, these are switch contact arrangements for a certain number of contact levers dimensioned. For a multi-rated current Series of low voltage circuit breakers are therefore correspondingly many different movable switch contact arrangements needed. The object of the invention is to achieve this underlying the manufacturing cost of this variety of To reduce switch contact arrangements.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Kontakthebelträger ein Mittelteil aufweist, bestehend aus einem Grundkörper und wenigstens einem an diesen anfügbaren Zusatzkörper, und daß beidseitig an dem Mittelteil die Lagerarme befestigt sind.According to the invention, this object is achieved in that the contact lever carrier has a central part consisting of a base body and at least one attachable to it Additional body, and that on both sides of the middle part Bearing arms are attached.
