MICROTEMP^®Thermal Cutoffs:

TECHNICAL DATA

MICROTEMP^®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.

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 fault conditions,

should be considered.
