5,Testing performance:
5.1 Tf-Rated functioning temperature
The temperature at which a Thermal Cutoff changes its state of conductivity to open circuitwith
detection current.The tolerance according to IEC691 is+0/-10℃
5.2 Fusing-off temperature:The fusing-off temperature indicates valuemeasured in silicon oil with a temperature increased by 0.5-1℃ per minute and a detective current 0.1 ampere or less.
5.3 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.
5.4 Tm -Maximum temperature limit:
The maximum temperature at whicha Thermal Cutoff canbe maintained for 10 minutes without re-
closing.This rating is required by safety standards based on IEC691.
5.5 In -Rated current
The allowable maximum current which a Thermal Cutoff is able to carry.
5.6 Un -Rated voltage
The allowable maximum voltage which a Thermal Cutoff is able to be applied.
