Abstract

Ein Niederspannungs-Leistungsschalter weist ein Formstoffgehäuse (10) auf, das aus zwei entlang einer Teilfuge (16) aneinander­ stoßenden Gehäuseteilen (12 und 14) besteht. Zwischen diese Gehäuseteile ist eine Trennwand (20) eingesetzt, die einen zur Aufnahme einer Antriebsvorrichtung dienenden Gehäuseraum (B) von einem die Schaltkontakte enthaltenden Raum (A) abtrennt. Die Trennwand (20) ist zugleich als Führungsorgan für Schaltgase ausgebildet und weist hierzu Abzugskanäle (32) auf. Zum Durch­ tritt von Kupplungsorganen zwischen den Schaltkontakten und der Antriebsvorrichtung sind von Vorsprüngen (44) flankierte Durch­ trittsöffnungen (40) vorgesehen. A low-voltage circuit breaker has a molded-plastic housing (10) on each other along a parting line (16) abutting housing parts (12 and 14). Between these A partition (20) is inserted into the housing parts housing space for receiving a drive device (B) from a room containing the switch contacts (A). The Partition (20) is also a guide for switching gases designed and for this purpose has discharge channels (32). To go through occurs from coupling elements between the switching contacts and the Drive devices are flanks flanked by projections (44) provided openings (40).
