Abstract

Eine Kontakthebelbaugruppe (10) eines Niederspannungs-Leistungsschalters weist parallele Kontakthebel (12) auf, die an einem Lagerbolzen (14) schwenkbar gelagert sind. Ein gegenseitiger Abstand zwischen den Kontakthebeln (12) wird durch einen Abstandshalter (16) aufrechterhalten, der zumindest zwei zwischen die Kontakthebel (12) zur Aufrechterhaltung des gegenseitigen Abstands eingreifende Trennstege (20) aufweist. Erfindungsgemäß ist der Abstandhalter (16) mit beiden Trennstegen (20) an dem Lagerbolzen (14) schwenkbar gelagert.

Figure imgaf001
A contact lever assembly (10) of a low-voltage circuit breaker has parallel contact levers (12) which are pivotally mounted on a bearing pin (14). A mutual distance between the contact levers (12) is maintained by a spacer (16) having at least two separating webs (20) engaging between the contact levers (12) to maintain mutual spacing. According to the invention, the spacer (16) with two separating webs (20) is pivotally mounted on the bearing pin (14).
