MICROTEMP
Thermal Cutoff
APPLICATION NOTES
®
MICROTEMP
thermal cutoffs, available in a variety of standard and custom configurations, provide
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 neces-
sary for both AC and DC applications. The following guidelines will answer most questions concern-
ing these two subjects.
Application of Thermal Cutoffs
A thermal measurement procedure that utilizes a Thermocoupled TCO Test Sample (TTTS) can
®
assist in determining the appropriate calibration temperature and design location of MICROTEMP
thermal cutoffs. The TTTS matches the electrical characteristics of the thermal cutoff but does not
have thermally responsive parts. The TTTS is supplied with a thermocouple attached to the case of
the thermal cutoff (see figure 5).

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.
Location
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 normal operation
and fault conditions, should be considered. The location that provides the largest differential
between these two conditions is generally most desirable.
