Bei Netzstörung wird der Speicher B über die Stromrichteranordnung SR entladen und der mechanische Schalter SW geöffnet. Das Öffnen dieses Schalters ist nicht kritisch, da zwischen Schalter SW und sicherer Schiene 55 eine Induktivitätsanordnung mit einem Hilfsschalter SE angeordnet ist. Bei einer Netzstörung (Hilfsschalter SE geöffnet) wird eine große Induktivität (13) der Induktivitätsanordnung wirksam, die im ungegtörten Netzzustand überbrückt ist. Daher sind im ungestörten Zustand nur geringe Induktivitäten (I1, I2) wirksam, über die aus dem Netz N ein hoher Strom fließen kann, der im Falle eines Verbraucherkurzschlusses zum Ansprechen der Verbrauchersicherungen (VS) ausreicht.
