*1 Part number indicates thermal cutoff with standard lead length. For long lead length type, type number is changed to SF**R1.
*2 Holding Temperature is the maximum temperature at which, when applying a rated current to the thermal cutoff, the state of conductivity
is not changed during specified time not less 168 hours(1week). The Th rating is only specified by UL.
*3 Maximum temperature limit is the temperature up to which thermal cutoffs will not change its state of cutoff without impairing.
*4 The electrical rating according to the various safety standards are shown in the following table.
*SF/R is available for 10A and 15A marking for PSE. Rating 10A marking is applied for Article, and 15A marking is applied
