Precautions When Using
Thermal Cutoffs
The following information describes the correct methods of us-
ing thermal cutoffs to insure proper and safe performance. To
achieve the full use and capacity of a thermal cutoff, it is nec-
essary for the customer to exercise proper storage and ex-
ecute appropriate circuit design, proper installation, and ad-
equate testing.
responsibility for problems which occur as a result of improper
storage and installation, or inappropriate circuit design, evaluations
or tests.
intended. Thermal cutoffs operate only when they sense an ambient
temperature greater than the factory pre-set temperature. They have
no ability to function by current overload and are not current limiting
devices.
tended to be used in the aerospace industry, aviation, nuclear power
generation systems, life support systems, engine control systems,
or safety control systems for transportation. Thermal cutoffs are ap-
plicable for electrical household devices, appliances and electron-
visual equipment, communication systems, measuring instruments
and specific transportation systems.

application and determine the proper mounting position and/or
method. To judge whether the selected thermal cutoff and chosen
position and method of mounting is suitable for the final application,
we recommend that the customer fully test and evaluate the unit in
an environment that duplicates the final application as closely as
possible. This includes mounting and securing the thermal cutoff
identically to the method that will be used in production.

C. Soldering
NOTE: The special sealant joining the lead wires to the case will soften
during soldering. Care must be taken to not move the leads or body dur-
ing the soldering process as the softened joints could shift and become
disconnected. The sealant will resume its initial strength after cooling.

minimum without moving it. Automatic wave soldered units must cool for
a minimum of 5 minutes.
When bending a lead, bend at a location 3mm minimum from the body
Take caution not to damage either the thermal cutoff body or the lead.
Keep the thermal cutoff body free from any push, pull or twist force.
Maximum soldering time is shown below.
During soldering, both the thermal cutoff body and leads should be free
After manual soldering, allow the thermal cutoff to cool for 30 seconds
Minimize the conduction of excessive heat to the thermal cutoff body
