ST01 series

    ST01 series



    KEY BENEFITS:
    1. First China-made round shape thermal protector got UL and 

    TUV certified and broke 30 years’ monopoly of Germany 

    protectors.

    2. Good sealed, can prevent product failure from vacuum 

    impregnation process.

    3. Small size, suitable to be embedded inside coil.
    4. Metal case, up to 50KG coil shaping pressure, has high 

    thermal conductivity and temperature sensitive.

    5. Pure temperature action type products, bimetal-disc

    without current and heat effect, accurate temperature control. 


    APPLICATION:1.  Motor   2. Transformers   3. Coils   

    4. Electronics, sensor

    Integration of resources:
    1. Integration of global supply chain resources, we buy

    bimetal-disc from the world’s largest bimetal-disc material 

    manufacturer EMS in the United States and case from German 

    supplier who uses stamping forming technology.

    2. Spring which material comes from NGK Japan and manufactured 
    by Japanese stamping supplier.
    3. Silver plating technology on case and spring which greatly 
    reduces the contact resistance.
    4. The key component bimetal-disc produced by fully automated 
    molding equipment and sorted by tunnel oven separation 
    equipment is good consistency and stable performance.
