| 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. |
