    Thermal Fuse Functions and Applications


    A thermal fuse functions by providing overheat protection for electrical products such as home appliances, battery packs, motors, power supplies, transformers, heating and air-conditioning equipment and various electronic devices. A thermal cutoff (TCO) is designed into electrical circuits to cutoff the electrical power in the circuit in case of overheating, either as a backup in series to a thermostat or on their own. Thermal cut-offs are used to prevent uncontrolled overheating.



    Features


    ¤ It is a non-resettable thermal links which uses fusible alloy for its thermal element.
    ¤ It does not contain lead (Pb) and cadmium (Cd) in compliance with RoHS.
    ¤ It does not contain 163 substances of very high concern (SVHC) that are specified by REACH as of Jun. 2015.
    ¤ Extremely simple construction ensures reliability, and hermetically sealed thermal element reduces deterioration with age.
    ¤ It has superior thermal sensitivity.
    ¤ It uses an insulating container.
    ¤ Please feel free to ask us about cutting, forming and taping of lead wire.

    Thermal links (Caution)


    The following describes the cautions for using thermal links.

    If the stipulations indicated in the cautions are not strictly observed, thermal cutoffs may function at temperatures lower than functioning temperatures shown in the specification, or they may not function at all even if they exceed the functioning temperatures. Problems resulting from improper use of thermal cutoffs are the responsibility of users, and not of Aolittel.

    1. The electrical rating and rated functioning temperatures of thermal cutoffs are prescribed. Use thermal cutoffs within the rating ranges.
    2. Install thermal cutoffs so that their temperatures do not continuously exceed the maximum use temperature indicated in the ratings table for each product series.
    3. Do not use thermal cutoffs in special conditions, where the use of ordinary electrical equipment such as consumer electronics and electronic office equipment is not appropriate. For example, the use in liquids, in organic solvent, in environments of corrosive gases (many sulfurous acid gas and nitrogen oxide gas), in high or low pressure, in high humidity, or in flammable environments shall be prohibited. Under such conditions, thermal cutoffs may function at temperatures lower than the functioning temperatures or they may not function even if they exceed the functioning temperatures because of hermetically damaged epoxy resin caused by its deterioration.
    4. Thermal cutoffs are developed under the assumption that will used in ordinary electrical equipment such as consumer electronics and electronic office equipment. Do not use them in aeronautical equipment, life-support equipment and other machinery for medical purposes, equipment used for engine control in transportation machinery, or in nuclear power equipment.
    5. To have thermal cutoffs function as they should, users must select the thermal cutoffs suited to each piece of equipment, and properly choose the positions and methods for installation. Users themselves should decide which type to install in each kind of equipment, and should avail themselves of not only information offered by Aolittel, but also,their own tests, to confirm that their selections are the best. Concerning these confirmations tests, make sure to perform the tests a sufficient number of times on the end products and to respect these tests under both normal and abnormal conditions.
    6. Care must be taken, when designing, for the fact that self-temperature rise by energizing will cause thermal cutoffs to function under less ambient temperature.
    7. Long-term exposure under high-temperature environment may cause thermal cutoffs to fuse off improperly due to thermal deterioration. Therefore, using thermal cutoffs at as low temperature as possible will be recommended. Maximum use temperature is the temperature at which we make sure improper function after specified time do not occur.

    When used in special conditions described in above item 3or 4, please consult a sales person of Aolittel.
