Abstract

Erste, zweite Leitungen (L1, L2) leiten die Eingangsgleichspannung (Ue) bis zur Last. Eine Sicherung (S) ist in Reihe in die erste Leitung geschaltet. Der Schaltkontakt (K11) eines ersten Relais (K1) ist in Reihe in die erste Leitung geschaltet und wird bei einem Abschaltvorgang geöffnet. Der Schaltkontakt (K21) eines zweiten Relais (K2) ist nach dem ersten Relais parallel zwischen erster und zweiter Leitung geschaltet und wird bei einem Abschaltvorgang im Anschluß an die Öffnung des ersten Relais geschlossen. Die Vorrichtung ist trotz Einsatz von handelsüblichen Relais hochverfügbar.
