This listing covers thermal fuses from Dongguan Yaxun Electronic Hardware Product Co. Ltd., including AUPO, NEC, RH and Emerson variants. The organic-type metal shell thermal fuse features a 10-component structure: pins (A and B), sealed resin, insulating ceramic, fine spring, star reed, coarse spring, wafer, temperature sensing block and housing. Current flows from the left pin through the sliding contact and metal housing to the right pin under normal operation; when external temperature reaches the set threshold, the organic material melts, releasing the compression spring and separating the sliding contact to permanently cut the circuit.
The easy-to-melt alloy wire thermal fuse variants use ceramic or square shells with a fusible alloy as the temperature-sensing element. The construction consists of symmetrical leads, the alloy wire and a resin mixture inside an insulated porcelain tube or plastic shell. When the alloy’s melting point is reached, surface tension in the liquefied resin pulls the molten wire into a spherical shape at both ends, breaking the circuit. Typical industry standards for thermal fuses include IEC 60691, which specifies safety provisions and operating tolerances.
These thermal fuses are used in appliances, motors, transformers and battery packs to prevent overheating. Buyers typically source them in bulk for OEM integration, with packaging and lead times confirmed directly with the supplier. The fuses are single-use, non-resettable devices designed for fail-safe thermal protection in electrical circuits.

Before ordering, verify the exact rated operating temperature (Tf), holding temperature (Th) and limit temperature (Tm) for your application. Request the supplier’s datasheet for the specific AUPO, NEC, RH or Emerson model to confirm these parameters match your thermal protection requirements.
Confirm logistics details such as lead time, Incoterms (e.g., FOB or CIF) and payment terms. Thermal fuses are typically shipped in bulk packaging, so discuss moisture protection and handling instructions to prevent damage during transit from China.
For quality checks, inspect the fuse’s structural integrity, shell material and pin alignment upon receipt. Request a certificate of compliance with IEC 60691 or equivalent standards. Functional testing under controlled conditions is advised to validate the fuse’s activation temperature and circuit interruption performance.
