Abstract

An overheating prevention system for an electric heater (esp. a flow-through heater), having an insulating body (10) with a connection element (14) and a contact arrangement (16, 17, 19) for electrical contact prodn. between the connection element (14) and a heating element (4), comprises a spring element (21) which is pre-tensioned in the contact opening direction and which, in the heater operating condition, is compressed into a contact closure state by an actuating element (22) directly supported on the heating element (4) by its end section (23) with a defined softening temp. Pref. the end section (23) consists of electrically non-conductive material, pref. fibre-reinforced plastic, esp. glass fibre-reinforced thermoplastic polyester, with a melting temp. of 210-240 (pref. 225) degrees C.
