Abstract

Die Erfindung bezieht sich auf eine Luftleiteinrichtung (9) zum Kühlen eines Schalterteiles eines elektrischen Schalters (1) mit zumindest einem Luftleitelement (13), das unter Bildung zumindest eines in Einbaulage des Schalters vertikal verlaufenden Luftkanals (37) in einem Abstand zu dem zu kühlenden Schalterteil angeordnet ist, wobei der Luftkanal (37) einen nach unten weisenden Einströmbereich (40) zum Einströmen von Kühlluft und einen nach oben weisendes Ausströmbereich (31) zum Ausströmen der Kühlluft aufweist.
Um die Wärmeabfuhr zu verbessern ist vorgesehen, das Luftleitelement (13) derart zu formen ist, dass sich der Einströmbereich (40) in Richtung auf den Ausströmbereich (31) verjüngt.
