NTE8070 thru NTE8242
Thermal Cutoff
(Thermal Fuse)
Description:
Nineteen Thermal Cutoffs (also known as Thermal Fuses) are now included in the NTE product line. They are miniature,
NONRESETTABLE temperature sensitive devices designed to prevent appliances and electronic equipment from over-
heating. NTE thermal cutoffs are UL and CSA listed.
Literally thousands of different applications have been devised for thermalcutoffs, thus providing a large replacement
market. Such applications include:
Hair Dryers
Refrigerators
Battery Chargers
Irons
Hot Plates
Glue Guns
Electric Motors
Window Fans
Coffee Makers
Microwave Ovens
Popcorn Poppers
Dishwashers
And hundreds of others
The TCO (Thermal CutOff) responds to temperature by interrupting an electrical circuit when the operating and/or envi-
ronmental temperature exceeds the thermal rating of the device. This is accomplished when the internal organic pellet
experiences a phase change, allowing the spring activated contacts to permanently open the circuit.

Note 1: Temperature sensitive devices. Do not store above +48
C (+120
F).
Note 2: Color Band does not denote temperature group.
Note 3: The electrical resistance of the NTE series thermal cutoff is comparable to that found in an equal length of 18 gauge solid copper wire. With
proper air flow, heat generation below 15 Amps is minimal, above 15Amps the upper limit on the currentcapacity will depend on the environment
for each specific application.
Note 4: A general rule of thumb for continuous operating temperature for thermal cutoffs is 30
C less than the Maximum Opening Temperature.
