Abstract

Elektrischer Durchlauferhitzer, insbesondere für Drehstromanschluß.
Ein solcher Durchlauferhitzer ist mit einer den Heizstromkreis mit Einleiten des Zapfvorganges schließenden mehrpoligen Betriebsschaltkontakteinrichtung und einer den Heizstromkreis allpolig unterbrechenden Sicherheitsschalteinrichtung ausgerüstet.
Um den konstruktiven Aufwand für beide Schalteinrichtungen zu verringern, ist die Betriebsschaltkontakteinrichtung (3) und die Sicherheitsschalteinrichtung (12) zu einer einzigen Schalt- bzw. Baueinheit vereinigt, wobei für beide Schalteinrichtungen eine gemeinsame Doppelschnappfeder-Kontaktanordnung vorgesehen ist.
Diese Maßnahme ermöglicht eine kompakte und raumsparende Ausbildung der den Heizstromkreis eines Durchlauferhitzers für Drehstromanschluß beherrschenden beiden Schalteinrichtungen.
