Abstract

Ein Leistungsschalter (1) weist eine Schaltkontaktanordnung (4) und eine diese betätigende Antriebsvorrichtung auf, wobei die Verbindung zwischen der Schaltkontaktanordnung (4) und der Antriebsvorrichtung lösbar ausgebildet ist. Hierzu enthält ein Kontaktträger (13) der Schaltkontaktanordnung (4) einen Koppelbolzen (14), der eine gelenkige Verbindung mit einer Hebelanordnung (16, 17, 18) der Antriebsvorrichtung herstellt. Durch ein Haltestück (28) ist eine Schaltwelle (8) der Antriebsvorrichtung in eine Stellung drehbar und in dieser Stellung zu fixieren, die ein problemloses Entfernen der Schaltkontaktanordnung (4) und anschließenden Ersatz durch eine andere Schaltkontaktanordnung (36) ermöglicht. Das Haltestück (28) ist nach Entfernen eines Bedienpultes (9) des Leistungsschalters (1) auf die Schaltelle aufzusetzen und wird an einem vorderen Gehäusekörper (3) des Leistungsschalters (1) dort befestigt, wo sonst das Bedienpult (9) aufliegt.

Figure 00000001
A circuit breaker (1) has a switch contact arrangement (4) and a drive device that actuates it, the connection between the switch contact arrangement (4) and the drive device being detachable. For this purpose, a contact carrier (13) of the switching contact arrangement (4) contains a coupling bolt (14) which creates an articulated connection with a lever arrangement (16, 17, 18) of the drive device. By means of a holding piece (28), a switching shaft (8) of the drive device can be rotated into a position and fixed in this position, which enables the switching contact arrangement (4) to be easily removed and then replaced by another switching contact arrangement (36). After removing a control panel (9) of the circuit breaker (1), the holding piece (28) is to be placed on the switching point and is attached to a front housing body (3) of the circuit breaker (1) where the control panel (9) otherwise rests.
