Abstract

Die Erfindung betrifft eine elektrische Heizvorrichtung, die folgende Merkmale aufweist:
  • wenigstens zwei Schalt- und Heizelemente (T1, T2, Tn; T1, T4, T5, Tn), die jeweils eine Ansteuerklemme (G) und eine Laststrecke (D-S) aufweisen, wobei die Laststrecken (D-S) der wenigstens zwei Schalt- und Heizelemente (T1, T2, Tn; T1, T4, T5, Tn) parallel geschaltet sind,
  • eine Sicherung (Si), die in Reihe zu den Laststrecken (D-S) der Schalt- und Heizelemente (T1, T2, Tn; T1, T4, T5, Tn) geschaltet ist, wobei die Reihenschaltung an eine Versorgungsspannung (V) angeschlossen ist,
  • eine an den Steueranschluss (G) wenigstens eines der Schalt- und Heizelemente (T1, T2, Tn; T1, T5, Tn) angeschlossene Schutzschaltung zum Einschalten des angeschlossenen Schalt- und Heizelements nach Maßgabe der Temperatur an wenigstens einem der Schaltelemente (T1, T2, Tn; T1, T4, Tn).
