Description
Product Description The 184°C Radial/Axial Thermal Fuse (TF RY 10A 250V) is a compact, non-resettable safety device designed to provide ultimate over-temperature protection in household appliances and electronics. Unlike a bimetallic thermostat that cycles open and closed, a thermal fuse functions as a one-time cutoff. It contains a heat-sensitive organic pellet or fusible alloy link that instantly melts when the ambient temperature reaches exactly 184 ∘ C (363 ∘ F), permanently opening the circuit to prevent an electrical fire. Once this fuse blows due to an alternate component failure or a runaway heating element, it must be cut out and replaced entirely to restore functionality to the machine. Key Specifications Model/Type Series: TF Series / RY Series / SEFUSE style Cutoff Temperature: 184 ∘ C (363 ∘ F) fixed threshold Voltage Rating: Up to 250V AC universal mains operation Current Capacity: 10A continuous maximum load resistance Structure: Solid metal barrel casing with axial wire leads Compatibility Guide Because thermal fuses are standardized safety components based entirely on maximum current capacity, voltage limits, and target cutoff temperature, they are universally compatible across thousands of appliance footprints. 1. Alternative Branding & Sourcing Equivalents This 184°C thermal cutoff can directly replace equivalent fuses from top safety component manufacturers, provided the temperature and amperage match: SEFUSE (NEC): SF184E / SF184Y Series Microtemp (Emerson): G4A00184C Series Local Component Outlets: Widely distributed by regional electronics suppliers like Duinolk and Tronic.lk in Sri Lanka, as well as global networks like Amazon and AliExpress. 2. Common Applications & Products A 184 ∘ C threshold is tailored specifically to protect medium-to-high heat kitchen and garment appliances, making it a crucial safety fallback in: Rice Cookers & Multi-Cookers: Tucked securely under the main heating plate inside traditional mechanical rice cookers to kill power if the main bimetal contact switch fails and the unit over-boils. Electric Irons & Garment Steamers: Clamped to the soleplate casting as a hard emergency backup if the adjustable dial thermostat welds shut. Coffee Makers & Percolators: Positioned flat against the aluminum element tubes to protect the plastic housing from melting if the reservoir runs completely dry. Coil-Heated Household Appliances: Found protecting small deep fryers, slow cookers, hot plates, and hair dryers. ⚠️ Important Installation Tip: Do not solder the replacement thermal fuse leads directly to the original wiring unless using extreme heat sinking. The heat from a standard soldering iron will travel down the wire leg, instantly melt the internal alloy pellet, and destroy the brand-new fuse before it is even installed. Always use mechanical crimp connectors or screw-down terminal blocks to join the wire leads safely.
