    BTT-10A Series Thermal Cutoff Description

    Thermal fuses, defined as non-resettable, are single action devices that are widely used for the electrical equipments against over temperature. The thermal cutoffs are composed of the fusible alloy with low melting point and special resin, encapsulated in a plastic or ceramic housing. Under normal operated, the fusible alloy is joined by the two lead wires within the housing. When the thermal cutoff senses an abnormal heat and reach a preset temperature, the fusible alloy melts and disconnects the circuit completely with the aid of the special resin. Both Axial and Radial shapes are available, with rated current from 1A to 200A, Function temperature 76℃~221℃, certificated including UL, cUL, VDE,TUV,PSE, KTL, CCC and RoHS, REACH Compliant.

    BTT-10A Series Thermal Cutoff Specification

    BTT-10A Series Thermal Cutoff


    1.Features
    With strong compact structures,high insulation

    resistance and quickly heated advantages
    can be quickly action
    when the products work under innormal or cant be reset,can soon out off the power.


    2.Application
    Widely used in follow various fields such as transformer,Explosion line,Exhaust fan,fan and small

    power motor charger,adeptor,Secondary battrery,Household combined with gas water heater lightings and various heater equipment and so on.


    3.SCOPE
    This Specification applies to BTT series Thermal Fuses.
    1.1General Information
    •Designed to EN60691( 72 °C–240 °C )
    •RoHS compliant and HF


    4. Part Numbering System


    BT is product code.



    6. Operating Principle


    Loaded themetal shell with movable electrode,spring and heat-variable fusion cake for RY series
    thermal fuse.Spring B is encased into it on the state of compression, that ’ scan make spring B use
    copper backing to stand up to movable electrode in order to contact with lead A.In the state of normal
    times,current will connect with lead B through lead A ,movable electrode and metal shell .


    When the environment temperature is greater than action temperature.The heat which through
    Lead and metal shell will make the heat-variable fusion cake meltin to liquid.At the same time,spring
    A and B will repristination,so spring A will push the movable electrode to direction of spring B,that’ s
    can cutoff the connection of spring A and cutoff the circuit .
