thermal cutoffs, available in a variety of standard and custom configurations, pro-
vide reliable one-shot, over-temperature protection in a wide range of applications. Performance
can be affected by installation method and proper location of the thermal cutoff. Both application
and installation are important in the overall performance of the product, and thorough testing is
necessary for both AC and DC applications. The following guidelines will answer most questions
concerning these two subjects.
Application of Thermal Cutoffs
A thermal measurement procedure that utilizes a “dummy” thermal cutoff can assist in determining
the appropriate calibration temperature and design location of MICROTEMP
thermal cutoffs. The
dummy matches the electrical characteristics of the thermal cutoff but does not have thermally
responsive parts. The dummy is supplied with a thermocouple attached to the case of the thermal
cutoff (see figure 8).

Dummy cutoffs can be supplied with Type J, Type T or Type K thermocouples. Other thermocouple
types can usually be supplied upon request at a nominal charge.
Sufficient time and effort must be used to determine the proper and most desirable location for a
thermal cutoff. The employment of infrared thermography, or a sufficient number of thermocouples
to identify the highest temperature areas in the product requiring protection during fault conditions,
should be considered.
