Temperature Rating (Tf):Rated opening temperature
Holding temperature (Th):Maximum temperature measured at the case end ofthe thermal cutoff at which the thermal cutoff can be maintained for a period for 168 hours without opening.
Maximum temperature (Tm):The maximum temperature at which a thermal cutoff can be maintained for10 minutes as an open circuit and can then be maintained at twice rated voltage for a period of 2 minutes during which its mechanical and electrical properties will not be impaired
Structure
Applied to over-heat protection for all kinds of low-power motors, coils and etc.
APPLIANCES - space heaters, irons, stoves, electric blankets, hair dryers, clothes dryers, cookers,
toaster ovens,crock pots, mixers, toasters,microwave ovens, etc.
MOTORS - air conditioners,copiers, fans, washing machines, compressors,etc.
ELECTRONICS - TVs,stereos, tape recorders,video recorders, fluorescent lamps, transformers, computers,
surge suppressors,telecommunication equipment, etc
Thermal Fuse Characteristics:
It consists of a sliding contact, a spring, and an electrically
nonconductive thermal pellet.
Before the thermal fuse is activated, current flows from the left lead to the sliding contact
and through the metal housing to the right lead. When the external temperature reaches
a predetermined temperature, the organic matter meltsand the compression spring
becomes loose. That is, the spring expands and the sliding contact
is separated from the
left lead. The circuit is opened and the current between the
sliding contact and the left lead
is cut off.
Precautions When Using Thermal Cutoffs
The following information describes the correct methods of using
thermal cutoffs to insure
proper and safe performance. To achieve the full use and capacity
of a thermal cutoff, it is
necessary for the customer to exercise proper storage and execute
appropriate circuit design,
proper installation, and adequate testing. Thermtrol Corporation
does not assume responsibility
for problems which occur as a result of improper storage and
installation, or inappropriate circuit
design, evaluations or tests.
• Do not use thermal cutoffs for purposes other than for what they
are 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.
• Do not use thermal cutoffs in equipment, appliances or devices
intended 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 applicable for electrical
household devices, appliances and electronics. Other applications
include: office automation equipment,
audiovisual equipment, communication systems, measuring instruments
and specific transportation systems.
• Do not use thermal cutoffs in applications exceeding the listed
ratings in the specification chart.
• Do not use thermal cutoffs in a liquid, in a corrosive atmosphere
such as sulfurous gas, or in a high
humidity environment.
• Customers shall choose the thermal cutoff appropriate for the
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.
