Rated functioning temperature
(T
f
)
The temperature at which a thermal cut off (TCO) 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
Holding temperature (T
h
)
The maximum temperature at which a thermal cut off can be maintained while conducting rated current for
168 hours which will not cause a change in state of conductivity to open circuit.
Max. overshoot temperature (T
m
)
Above this temperature the thermal cut off might conduct again
Rated current
The maximum current which the thermal cut off is able to carry for a specified time at T
