| Precautions
for handling
1. When the current exceeds the rated value, the thermal
fuse will activate at a lower temperature than the
fusing preset temperature. Check to be sure that the
current does not exceed the switching capacity.
2. Unexpected force or shock during transportation
or mounting may cause breakage of the thermal fuse.
Furthermore, if the ambient temperature goes up, it
may lead to an accidental fusing at a lower temperature.
So, be careful regarding the ambient temperature.
3. Keep the temperature sensor (protection tube) horizontal
or pointing downward (lead wire will be at the top)
when in use. If it is used with the temperature sensor
up, it may cause a malfunction.
4. Do not use in an environment where vibration or
shock is constantly applied.
5. Watch for other heat sources, and try to avoid
thermal interference. Be careful of fuse malfunction
due to unexpected other heat sources.

Caution
1. For storage, avoid high temperature
places.
2. Ceramic protection cylinders tends to crack.
So, be careful when handling.
3. Do not use the fuse without the protection tube.
4. Keep the load current within the rated value.
In principle, the temperature fuse is meant to be
used as a fail safe measure. The correct system design
is such that a thermostat is used for temperature
control and a temperature fuse activates if the thermostat
becomes defective.
