Abstract
Description
Claims (5)
einem Stromeingang (31),
einer Mehrzahl von mit dem Stromeingang (31) verbindbaren Stromaus gängen (37 bis 40) zur Stromversorgung daran angeschlossener Verbraucher, und
einer Stromzufuhr-Steuereinrichtung (36, 45, 46) zum Steuern eines Stromflusses zwischen dem Stromeingang (31) und den damit verbundenen Stromausgängen (37 bis 40), wobei
an den Stromausgängen (37 bis 40) jeweils eine mit der Stromzufuhr- Steuereinrichtung (36, 45, 46) verbundene Fehlerstromdetektoreinrichtung (41 bis 44) vorgesehen ist, mittels der eine hinsichtlich Betrag und Fließrichtung al ler zwischen dem jeweiligen Stromausgang (37 bis 40) und damit verbundenen Verbrauchern fließenden Einzelströmen repräsentative Stromsumme erfassbar, ein zur erfassten Stromsumme proportionales Fehlerstromsignal erzeugbar, und das erzeugte Fehlerstromsignal der Stromzufuhr-Steuereinrichtung (36, 45, 46) zuführbar ist, wobei
der Stromfluss durch die Stromzufuhr-Steuereinrichtung (36, 45, 46) un terbrechbar ist, wenn eines der ihr von den jeweiligen Fehlerstromdetektorein richtungen (41 bis 44) zugeführten Fehlerstromsignale einen vorgebbaren Feh lerstromsignal-Schwellenwert überschreitet.
