Abstract

Bei einer zur Temperaturbegrenzung dienenden elektri­ schen Schmelzsicherung mit einem geschlossenen Gehäuse (1), in welchem ein Federmechanismus (2, 3, 4) einen elektrischen Kontakt unterbricht, sobald ein als Auflage für den Federmechanismus dienender Schmelzkörper (6) flüssig wird und den Federmechanismus entlastet, besteht der Schmelzkörper im wesentlichen aus einer gesättigten alipha­ tischen Dicarbonsäure mit 4 bis 14 Kohlenstoffatomen. In the case of a temperature limiting electri fuse with a closed housing (1), in which a spring mechanism (2, 3, 4) one electrical contact is interrupted as soon as a support for the melting mechanism (6) serving as the spring mechanism is liquid is and relieves the spring mechanism, there is Fusion body essentially from a saturated alipha table dicarboxylic acid with 4 to 14 carbon atoms.
