The HCET-A-S01 is a revolutionary round-shaped thermal protector, the first of its kind made in China to achieve UL, TUV, and CQC certifications. It breaks the 30-year monopoly held by German manufacturers, offering a superior and reliable solution for thermal protection. Its well-sealed design prevents issues during vacuum impregnation processes, making it ideal for embedding within electric motor coils. The robust metal case can withstand up to 50KG of coil shaping pressure, ensuring high thermal conductivity and precise temperature sensitivity for accurate motor overload protection.
