Thermal Cutoffs (TCO)
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
✽
1 Rated Functioning Temperature (Tf)
The temperature at which a TCO changes its state of conductivity to open circuit with loading detection current only.
Tolerance;

; ±7 °C
UL,CSA,VDE, BEAB, CCC;
–10
°C
✽
2 Functioning Temperature (Fusing-off temperature)
The functioning temperature at which a TCO changes its state of conductivity to open circuit in the ambient air oven which increases
temperature by 1 °C per minute and with loading the detective current 0.1 A or less.
✽
3 Maximum Operating Temperature.
The maximum temperature at which a TCO can be maintained while conducting rated current for 1000 h.
For details please refer to specifi cation.
✽
4 Holding Temperature (Th)
The maximum temperature at which a TCO can be maintained while conducting rated current for 168 h which will not cause a change in
state of conductivity to open circuit.
✽
5 Maximum Temperature Limit (Tm)
The maximum temperature at which a TCO can maintains its mechanical and electrical properties with out closing again for 10
minutes after a TCO has changed its state of conductivity.
