Abstract

Die vorliegende Erfindung betrifft einen Fehlerstromschutzschalter aufweisend einen Summenstromwandler (18), eine Auswerteelektronik (12), wenigstens ein erstes bewegliches Kontaktelement (1), welches mit einer Kraft beaufschlagt ist, wenigstens ein zweites Kontaktelement (2), welches mit dem wenigstens einen ersten Kontaktelement (1) elektrisch verbindbar ist, eine Auslösemechanik (3) zur Entriegelung des wenigstens einen ersten beweglichen Kontaktelementes (1), sowie eine Steuereinheit (11), die über eine Steuerleitung (15) mit dem Summenstromwandler (18) verbunden ist, und eine Prüfungseinrichtung, mit einem Prüfwiderstand (13) und einer Prüftaste (14), zur Erzeugung eines definierten Fehlerstromes, bei dem das wenigstens eine zweite Kontaktelement (2) beweglich gelagert und mit einer Kraft beaufschlagt ist, um der Bewegung des wenigstens einen ersten beweglichen Kontaktelementes (1) folgen zu können, dass Begrenzungsmittel vorgesehen sind, um die Bewegung des wenigstens einen ersten beweglichen Kontaktelementes zu begrenzen, und dass Überprüfungsmittel zur Feststellung der Bewegung des wenigstens einen zweiten beweglichen Kontaktelementes vorgesehen sind. Ferner betrifft die Erfindung ein Verfahren zum Durchführen eines Selbsttestes eines derartigen Fehlerstromschutzschalters.
