Abstract

Elektrischer Durchlauferhitzer, insbesondere für Drehstromanschluß. Electric instantaneous water heater, especially for three-phase connection.

Ein solcher Durchlauferhitzer ist mit einer den Heizstromkreis mit Einleiten des Zapfvorganges schließenden mehrpoligen Betriebsschaltkontakteinrichtung und einer den Heizstromkreis allpolig unterbrechenden Sicherheitsschalteinrichtung ausgerüstet. Such a water heater is with the heating circuit Initiate the tapping process closing multi-pole Operating switch contact device and the heating circuit all-pole interrupting safety switching device.

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. To the design effort for both switching devices reduce, is the operational switch contact device (3) and Safety switching device (12) to a single switching or Unit combined, one for both switching devices common double snap spring contact arrangement is provided.

Diese Maßnahme ermöglicht eine kompakte und raumsparende Ausbildung der den Heizstromkreis eines Durchlauferhitzers für Drehstromanschluß beherrschenden beiden Schalteinrichtungen. This measure enables a compact and space-saving training which is the heating circuit of a water heater for Three switching devices dominating two switching devices.
