Prinzip der ***Fehlerstrom-Schutzschaltung***

Bei Körperschluss muss der Fehlerstrom gegen Erde so groß sein, dass derAuslösefehlernennstrom der Fehlerstrom-Schutzeinrichtung zum Fließen kommt unddurch den Summenstromwandler die Auslösung erfolgt. Der Erdungswiderstand derAnlage darf gemäß ÖVE/ÖNorm E 8001-1 maximal 100 Ohm betragen.

residual current protective device


Explanation:
This term would cover different types of protective devices (GFCI, circuit breaker, etc.).

agree  Schtroumpf: See IATE, "residual current-operated protective device". The device idea is a good solution for the Schalter/SchaltUNG-issue.

Principles of residual current protection


Explanation:
I believe it's the theory behind protection rather than any specific devices...

fault current protection


Explanation:
This is referring to the concept as opposed to a specific device for fault currents.

ground fault circuit interrupter


Explanation:
In the USA, this is what this thing is called. The outlets are mandatory in every bathroom, as far as I know.
This link says:
The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second.

So, dropping a toaster into the full bathtub will no longer send Uncle Joe to his last reward, regardless of what you see in the movies.

residual-current protective circuit


Explanation:
Please distinguish "Schutzschalter" and "Schutzschaltung". Teh latter is no device, but an circuit.

The additional equipotential link between the support element and the main protection circuit. (whether this is created using exposed conductive parts or conductors] must be sized according to the maximum current, which is equal to the sum of the currents of each of the devices fixed on, in accordance with the table on page 34.

If the power generator is equipped with a residual-current protective circuit, the star point of the generator must be connected to the casing of the power generator, and via the earthing screw to a suitable potential equalisation conductor.

The protective earthing measure can be problematic however, since the rapid activation of the overcurrent protective device requires extremely high currents, which in turn require the lowest possible earthing resistances. If stronger electric circuits are required, it will be necessary to resort to a Residual Current Protective Device. The strength of the release current is also dependent on the earthing conditions where the residual-current protective circuit is concerned.

The type of protection used is the residual-current protective circuit (tripping current 30 mA).
https://www.augsbow.de/wp-content/uploads/2019/05/ABO20-10_P...

Ensure that the device is protected via a residual-current protective circuit with a rated residual current of maximum 30Ma.

Zwischenzeitlich habe ich auch eine Beschreibung dieser Schutzschaltung im Internet gefunden, die meine Aussagen (vgl. Diskussion) voll bestätigen:

VII Fehlerspannungs(FU)-Schutzschaltung.
Die Fehlerspannungsschutzschaltung schaltet den überwachten Verbraucher ab, wenn durch Isolationsfehler die Fehlerspannung auf 65 V ansteigt.
Die Fehlerspannungsspule F ist durch einen Schutzleiter SL mit den zu überwachenden Metallteilen des Verbrauchers (Motorgehäuse) verbunden. Die andere Spulenseite liegt über einen Hilfserdungsleiter D an einer Hilfserde RH. Wenn die Berührungsspannung zu hohe Werte annimmt, wir die Spule F erregt und löst über ein Schaltschloß den Fehlerspannungsschutzschalter aus und schaltet den Körperschluß ab. Die Abschaltung erfolgt allpolig; auch der Nulleiter wird, falls er angeschlossen ist, abgetrennt.

Anm.: Das Schaltbild zeigt die gleiche Konfiguration wie in meinem Fachbuch.

Bitte den Nachtrag nicht beachten! Er gehört zu "FU-Schutzschaltung" und wurde irtümlicherweise hier gepostet.
