Temperaturbegrenzer/ -sicherungskombination "Duomelt Plus" Typ 162 441

Type 162 441

Temperature limiter / thermal link combination "Duomelt Plus"

The triple combination limiter / limiter / thermal link 162 441 is suitable wherever the heating phases in an electrical appliance must be interrupted permanently when a preset temperature is reached and where a maximum temperature must not be exceeded. Typical applications are sterilisers, steam presses, etc.

Bimetal discs are used as temperature sensing elements. The discs are pressed directly against the mounting plate of the combination and can therefore react quickly to changes in temperature. As soon as the individual preset temperatures are reached, the bimetal discs operate and open the relevant electrical contacts, opening the circuit. On cooling steel discs prevent the temperature limiters from resetting automatically. The limiters must be reset manually by pressing the reset tabs.

The thermal link has a melt solder insert, which via the baseplate is in direct contact with the surface to be monitored. When the preset temperature is reached, the solder melts, opening the electrical contacts permanently. Resetting is not possible. When the fault has been removed, the thermal link must be replaced.

  • 3 integrated functions
  • Easy mounting and wiring
  • Fast thermal response, independent of mounting position
  • High force to open contact
  • Long life
  • Various types of terminals and fixing
