Claims (2)

Patentansprüche:
1. Installationsselbstschalter mit Differentialrelais, dadurch gekennzeichnet, daß ein schwingungsfähiger Anker (11) dem Magnetfeld des in die Stromleitungen des Schalters eingeschalteten Differentialrelais (7) derart ausgesetzt jst, daß er bei unsymmetrischer Stromentnahme in Schwingung gerät und dadurch durch Betätigung eines Auslösehebels (14) die Kontakte (3, 4) des Schalters öffnet.
2. Installationsselbstschalter nach Anspruch 1, dadurch gekennzeichnet, daß bei gegeneinander stromdurchflossenen Differentialrelaiswicklungen die Drähte parallel zueinander auf dem Relaiskern gewickelt sind, derart, daß das Streufeld des Magnetfeldes aufgehoben ist. no
