Rated functioning temperature(Tf)¡G
The temperature at which a Thermal Cutoff changes its state of conductivity to open circuit detection curret.The tolerance according to IEC60691 is from +0 to-10¢J.(With Japan Electrical Appliance and Material Law,on the other hand,they must function in the tolerance range of ¡Ó7¢J.).
Fusing(cut)-off temperature¡G
The fusing-off temperature indicates value measured in silicon oil with a temperature increased by 0.5-1¢J per minute and a detective current 100mA or less.
Holding temperature(Th)¡G
The maximum temperature at which a thermal Cutoff will not cause a change in state of conductivity to open circuit while conducting rated current for 168 hours. This rating is required by safety standards based on IEC60691.
Maximum temperature limit(Tm)¡G
The maximum temperature at which a Thermal Cutoff can be maimtained for 10 minutes without reclosing.This rating is requirde by safety standards based on IEC60691.
Rated current(Ir)¡G The allowable maximum current which a Thermal Cutoff is able to carry.
Rated current(Ur)¡G

The allowable maximum voltage which a Thermal Cutoff is able to be applied.
