thermal fuse / axial

The rated functioning temperature (TF) with thermal cutoff has an upper limit temperature at the rate of 0.25 to 1°C per minute and a detection current of 0.1A or less. However, the tolerance range of functioning temperature is +0 to -7°C. The rated holding temperature (TH) or the temperature do not function when the conducting rated current for 168 hours. Th and Tm are the standard ratings measured in IEC, UL, CSA safety standards. The maximum temperature limit (TM) in which a thermal cutoff can be held without any mechanical or electrical impairment is 10 minutes.
