Thermostat switch (NO)

KTS 111

The mechanical NO thermostat closes when the temperature rises and is used to control filter fans, heat exchangers, cooling devices or to switch signal transmitters when the temperature is exceeded. The use of push-in terminals prevents the supply lines from coming loose.

  • Fixed supply lines thanks to push-in terminals
  • Time saving thanks to tool-free connection
  • Large adjustment wheel enables convenient adjustablility
  • Optimized air intake
  • Can be used at altitudes of up to 5000 meters

NoteOvervoltage category: II: up to 5000 m; III: up to 2000 m.;The controller's contact system is exposed to the effects of the environment, which can change the contact resistance. This can lead to a voltage drop and/or self-heating of the contacts. Stripped length of rigid wire cable: 8 to 12 mm. Wire end ferrules (square or trapezoidal crimped) must be used for connections with stranded wires. Length of wire end ferrule: 8 mm or 12 mm. The height of the current has an influence on the tolerance accuracy, values specified: Switching resistive load (switching inductive load).
