Twenty One Thermal Cut−offs (also known as Thermal Fuses) are now included in the NTE product line. They are miniature, NON−RESETTABLE temperature sensitive devices designed to prevent appliances and electronic equipment from overheating. NTE thermal cutoffs are UL and CSA listed.
Literally thousands of different applications have been devised for thermal−cutoffs, thus providing a large replacement market. Such applications include:
The TCO (Thermal Cut−Off) responds to temperature by interrupting an electrical circuit when the operating and/or environmental 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.
