Abstract

Eine Kontakthebelbaugruppe (1) eines Niederspannungs-Leistungsschalters weist parallele Kontakthebel (3) auf, die an einem Träger (2) aus Isolierstoff schwenkbar gelagert sind. Ein gegenseitiger Abstand zwischen den Kontakthebeln wird durch einen Abstandshalter (6) aufrechterhalten, der als gesondertes Teil aus einem Kunststoff hergestellt ist, der geringe Materialdicken ermöglicht. Seitliche Wangen (10) des Abstandshalters (6) überdecken den Lagerbolzen (4) der Kontakthebel (3).
