Overview
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℃.(With Japan Electrical Appliance and Material Law,on the other hand,they must function in the tolerance range of ±7℃.).

Rated functioning temperature(Tf): |
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℃.(With Japan Electrical Appliance and Material Law,on the other hand,they must function in the tolerance range of ±7℃.).
|
Fusing(cut)-off temperature: |
The fusing-off temperature indicates value measured in silicon oil with a temperature increased by 0.5-1℃ per minute and a detective current 100mA or less.
|
Holding temperature(Th): |
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): |
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): | The allowable maximum current which a Thermal Cutoff is able to carry. |
Rated current(Ur): | The allowable maximum voltage which a Thermal Cutoff is able to be applied. |
