✽1 Rated Functioning Temperature (UL: TF, CSA,VDE, BEAB, CCC: Tf)

The temperature at which a TCO changes its state of conductivity to open circuit with loading detection current only.

Tolerance;

PS

E

; ±7 °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 3000 h (N, F, E, H series) or 1000 h (ML, MU

series) For details please refer to specification.

✽4 Holding Temperature (UL: TH, CSA: Th, VDE, BEAB, CCC: Tc)

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 (UL: TM, CSA,VDE, BEAB, CCC: Tm)

The maximum temperature at which a TCO can maintains its mechanical and electrical properties without closing again for 10

minutes after a TCO has changed its state of conductivity.
