Abstract

Ein Fehlerstrom-Schutzschalter mit einem Summen-Stromwandler (RK, W, SC) für zu überwachende Leitungen (L1, N), welche über die Kontakte eines mehrpoligen, ersten Schalters (S1) geführt sind, wobei dieser Schalter in seiner Schließstellung von einem Schaltschloss (SC) gehalten ist, welches bei Überschreiten einer vorgegebenen Stromdifferenz in den Leitungen den Schalter im Sinne eines Öffnens seiner Kontakte auslöst, und mit einem zweiten, als Prüftaster ausgebildeten Schalter (S2), bei dessen Schließen ein definierter, zum Auslösen des Schalters hinreichender Fehlstrom von einem Leiter abgezweigt wird, und mit Überbrückungszweigen (Z1, ZN) zur vorübergehenden Überbrückung der Kontaktstrecken des ersten mehrpoligen Schalters (S1), bei welchem die Überbrückungszweige (Z1, ZN) je eine Wicklung eines Symmetriertransformators (SW; SW1, SW2) enthalten oder die Umschaltkontakte eines dritten mehrpoligen Schalters (S3) zwischen dem Summenstromwandler (RK, W, SC) und den netzseitig gelegenen Kontakten des ersten mehrpoligen Schalters (S1) angeordnet sind und eine Verriegelung (VG) vorgesehen ist, welche bei ausgelöstem erstem Schalter (S1) eine Betätigung des dritten mehrpoligen Schalters (S3) verhindert.
