Fusing(Cut)-off temperature: The Fusing-off temperature indicates value measured in silicon oil with a temperature increased by 0.5-1degree per minute and a detective current 100mA or less. TH/TC-Holding temperature: 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 IEC691. TM/Tm - Maximum temperature limit: The maximum temperature at which a Thermal Cutoff can be maintained for 10 minutes without reclosing.This rating is required by safety standards based on IEC691 Ir - Rated current: The allowable maximum current which a Thermal Cutoff is able to carry Ur - Rated voltage: The allowable maximum voltage which a Thermal Cutoff is able to be applied.
