Product description

  • Temperature limiter (with manual reset)
  • –10...+15 °C/ +14...+59 °F,
    factory setting w = +5 °C (+41 °F)
  • Switching capacity:
    10 (2) A, AC 250 V;
    due to the gold-plated contacts, also
    switching of signal voltages < 24 V
  • Switching differential: 2 ± 1 K (3.6 ± 1.8 °F)
  • Capillary tube length: 0.6 m
  • Sensing response length: approx. 40 cm
  • Capillary: copper
  • Permissible medium: air
  • IP65
Mechanical frost protection thermostat/frost monitor THERMASREG® FST with switching output, fully active sensor rod, automatic reset or mechanical interlock with manual reset, available in capillary lengths of 0.6 m, 1.8 m, 3 m, 6 m, 12 m.



The frost protection monitor is suitable for air or water-side temperature monitoring of heat exchangers, water circulation systems and heating registers against freezing and for preventing frost damage, e.g. in ventilation and air conditioning ducts. It is intrinsically safe, with sensor break detection. If the capillary tube membrane system is damaged, the frost sensor automatically switches to the heating function. The FST 3 is also suitable for monitoring liquids. The sensor tube can be installed in an immersion sleeve. The delivery includes mounting clamps MK-05-K.
