¡Ý RATED FUNCTIONING TEMPERATURE (TF, Tf)

The temperature at which a thermal cutoff changes its state of conductivity to open circuit with detection current as the only load. The tolerance according to UL 1020 is
+ 0, - 10 C.

 ¡Ý HOLDING TEMPERATURE (TH, Tc)

The maximum temperature at which a thermal cutoff can be maintained while conducting rated current for 168 hours which will not cause a change in state of conductivity to open circuit.

 ¡Ý RATED CURRENT

The maximum current which the thermal cutoff is able to carry for a specified time at Tc without alteration of its Functioning Temperature.

 ¡Ý INTERRUPTING CURRENT

The value of the current that the thermal cutoff is capable of interrupting safely at rated voltage and under specified circuit conditions.

 ¡Ý TRANSIENT OVERLOAD CURRENT

A direct-current pulse train which the thermal cutoff is able to withstand without impairing its characteristics.

 ¡Ý RATED VOLTAGE

The voltage used to classify a thermal cutoff.
