3.2 Intended use

The model TFS35 bimetal temperature switches are used to limit temperatures within a
wide variety of industrial applications. The TFS35 are temperature limiting instruments.
They are not intended to provide any safety or protective functionality. They are
designed for use in environments up to pollution degree 2.
They monitor the temperature of machinery and equipment during normal operation
and, for example, switch off machinery if it overheats.
Bimetals form the basis of the model TFS35 temperature switches. Temperature
sensing is carried out by a bimetal disc, which snaps over when the Nominal Switching
Temperature (NST) is reached. After cooling back down to the reset switching
temperature (RST), the switch returns to its original state, so that the monitored
equipment can again work normally.
