Thermal Cutoffs (Thermal Fuses and Breakers)
Thermal Cutoffs (Thermal Fuses) are devices designed to keep components safe in situations when an excessive temperature occurs. When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current.
