Abstract

Erfindungsgemäß wird eine Schützsicherheitskombination aus zwei Schützen (1, 3) und einem zwischen beiden gekoppelten, mechanisch ausgeführten Verriegelungsbaustein (5) aufgebaut, wobei handelsübliche und beliebig große Schütze verwendet werden können, d.h. auch leistungsstarke Verbraucher sind damit schaltbar. Zugleich wird bei dieser Lösung ein herkömmlicherweise zur Verriegelung eingesetztes drittes Schütz eingespart.
