The KMF series of failsafe manual reset thermostats available from Practical Control Solutions , monitor temperatures in furnaces, ovens, kilns, boilers or any application where an over temperature condition would result in a critical failure.

The KMF series of failsafe manual reset thermostats work on the principle of liquid expansion from a bulb into a capillary which actuates a micro switch contact.

If the set temperature is reached the thermostat contacts switch and the unit latches out, with the contact switching generally used to shut down the system and return it to a safe state. The thermostat is reset manually by a pushbutton once the over temperature condition has cleared.

In the event of damage to the capillary or bulb the contacts open and return to their safe state. Switching set point is set through a calibrated dial. Two temperature ranges are available, +20…+150°C and +50…+300°C.
