Temperaturbegrenzer/ -sicherungskombination "Discomelt Plus" Typ 162 491

Type 162 491

Temperature limiter / thermal link combination "Discomelt Plus"

The temperature limiter / thermal link combination 162 491 is suitable wherever the power supply 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 e.g. electric kettles and coffeemakers with thermos flask.

A bimetal disc is used as a temperature sensing element. In any position, this disc is pressed directly against the mounting plate of the combination and can therefore react quickly to changes in temperature. As soon as the preset temperature is reached the bimetal disc operates and opens the electrical contact, interrupting the circuit. On cooling the disc snaps back into the original position, closing the circuit again. A steel disc prevents the temperature limiter from resetting automatically. It must be reset manually by pressing the reset tab.

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.

  • 2 integrated functions
  • Easy mounting and wiring
  • Fast thermal response, independent of mounting position
  • Equal heat transmission for limiter and thermal link
  • High holding temperature
  • Long life
  • Various types of terminals and fixing
