** Tm of SW-128T & 139T, approved by UL, 370°C

Rated functioning temperature

)

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

)

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

)

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

without alteration

of its functioning temperature
