UL certified fuse link

UL certified fuse linkTypical basic components: fuse link, of which the fuse link is its main core component. Different models of fuse links have different operating temperatures and maximum operating environment temperatures. The commonly used operating temperatures for fuse links are74℃～232Between ℃, the ambient temperature range is38℃～182Between ℃. When a fire breaks out, the fuse will open,

Temperature controlled melting alloy is both a temperature controlled alloy and a welding material. It can not only control temperature but also be welded, with multiple functions and wide applications. User units can use temperature controlled melting alloys to make various shapes, specifications, and temperature controlled elements with different melting points according to their respective product needs.

70Degree~280Du brass/Copper melting fuse, used for fire smoke exhaust and fire dampers, fire sprinklers, and melting pipes in air conditioning units/The temperature sensor, after reaching the corresponding temperature, the melting plate automatically melts, the temperature sensor automatically opens, and the mechanism works to achieve the expected safety effect.

How can we ensure that the melting point of thermal sensitive components made of temperature controlled melting alloys is both accurate and sensitive?“Five levels”.
①The selection of materials must be precise and pure, and the composition of metal elements must meet the requirements99.99%above;

②The quantity ratio of metal elements should be precise, with an error of less than0.1%； 
③adoptThe process of smelting should be done at the right time, and the time should not be too long or too short;

④The sequence of metal elements entering the furnace cannot be reversed and must be done step by step; 
⑤Welding implementation“Four determinations”Fixed personnel, fixed time, fixed temperature, and fixed quantity.

These five links are interconnected and interact with each other, influencing each other. Any deviation in one link will directly affect the accuracy of melting temperature and melting time. Only by correctly grasping this“Five levels”Only then can the melting temperature of the alloy be controlled from the solid phase line to the liquid phase line60sto120sEnsure that the thermistor operates accurately within the preset temperature range.
