Abstract

Die Erfindung betrifft einen Fehlerstromschutzschalter, der in einem aus flachen Halbschalen gebildeten Isolier­ gehäuse in Schmalbauweise untergebracht ist und An­ schlußklemmen für den Zugang und den Abgang wenigstens einer Phase un eines Neutralleiters aufweist.
Ferner besitzt der Fehlerstromschutzschalter eine aus einem Prüfstromkreis und einer an der frontseitigen Schmalseite des Gehäuses angeordneten Prüftaste gebilde­ ten Prüfeinrichtung. Hierbei ist der Prüfstromkreis von einer die phasenseitigen Anschlußklemmen verbindenden Kontaktanordnung zu einer der Anschlußklemmen für den Neutralleiter geführt. Er weist zwei Unterbrechungsstel­ len auf, von denen eine durch Betätigung der Prüftaste schließbar ist. Dabei ist der Prüfstromkreis in einer in die Flachseite (14) einer Halbschalte des Gehäuses (12) eingeformten Einformung (16) angeordnet, wobei die zur Betätigung des Prüfstromkreises (20) vorgesehene Prüfta­ ste (18) in einer in der Halbschale angeformten Führung (17) geführt ist.
