Abstract

The electronic system of the faulty current protective circuit breaker is series connected and provides an automatic reclosing after a short delay period. The circuit breaker is suitable for application in unattended electric installations if the electronic system after several attempts can not provide permanent reclosing, the protected installation remains disconnected. The circuit breaker has manual switching override and a testing push-button.

Description

Fehlerstromschutzschalter mit selbsttätiger WiedereinschaltungResidual current circuit breaker with automatic restart

Allgemeine Beschreibung: Zweck dieser Neuerung ist es, einen Fehlerstromschutzschal ter zu haben, der sich nach auftreten eines vorübergehenden Fehlerstromes selbsttätig abschaltet und nach einer kurzen Verzögerungszeit wieder einschaltet.General description: The purpose of this innovation is to provide a residual current protective device to have ter, which automatically after the occurrence of a temporary fault current switches off and switches on again after a short delay time.

Der Einsatz dieses Schalters ist überall dort zweckmäßig wo Elektroanlagen unbeaufsichtigt im Betrieb sind z.B.The use of this switch is practical wherever electrical systems unsupervised in operation are e.g.

i" 'woxherlendhäuserrl uder wdurend eines Urlaubs.i "'woxherlendhäuserrluder during a vacation.

Erfolgt während der Abwesenheit eine Abschaltung der Anlage durch Blitzschlag oder andereGründe, kann dies größere Schäden mit sich bringen z.B. der Inhalt von Kühlgeräten verdirbt oder im Winter kann die Zentralheizung einfrieren usw.If the system is switched off during the absence Lightning strike or other reasons, this can cause greater damage, e.g. the The contents of refrigerators spoil or the central heating can freeze in winter etc.

Für diesen Fall würde ein Fehlerstromschutzschalter mit selbsttätiger Wiedereinschaltung die Anlage nach einer kurzen Verzögerungszeit wieder in Betrieb setzen.In this case, a residual current circuit breaker with an automatic Restart, the system is back in operation after a short delay set.

Die Wiedereinschaltung wird durch die im Schalter eingebaute Elektronik (1) mehrmals versucht.Hält der Fehlerstromschutzschalter nach mehrmaligem Einschal tversuch nicht, z.B. wegen vorhandenseins eines beständigen Fehlerstromes, bleibt die Anlage außer Betrieb.The switch-on is activated by the electronics built into the switch (1) Tried several times The residual current circuit breaker stops after being switched on several times The attempt does not remain, e.g. due to the presence of a constant fault current the system out of operation.

Der Schalter (2) ist für manuelle Aus/Einschaltung vorgesehen.The switch (2) is intended for manual on / off switching.

Die Taste (3) ist als Prüftaste für den Schalter gedacht.The button (3) is intended as a test button for the switch.
