LEAO, 染, 松下, SWC Limiter熱熔斷器

The fuse materials used in LEAO, 染, 松下, SWC thermal fuses include copper, aluminum, iron and other elements, and copper is one of the most widely used materials. Copper fuses can be quickly melted when the current is overloaded due to their excellent conductivity, solid texture, good oxidation resistance and high temperature resistance. Thus, electrical equipment is effectively protected and electrical safety is ensured.

LEAO中使用嘅熔体材料, 染, 松下, SWC熱熔斷器喺熱熔斷器嘅性能中起著至關重要的作用，係成個設備嘅核心部件之一. 根據熔體材料嘅特性, 我哋可以把它們分為兩類: 低熔點和高熔點. Low melting point materials represented by tin and lead are usually made into the thickest cross-sectional shape because of their easy melting and relatively large resistivity characteristics, so the amount of metal vapor generated during the melting process is relatively large. These specific properties make this type of material more suitable for thermal fuse structures with lower breaking capacity. 另一方面, high melting point materials, such as copper and silver, are more suitable for making smaller cross-sectional sizes because they are not easy to melt and have relatively low resistivity. 另外, relatively less metal vapor is generated during the melting process, so this type of material is more suitable for use in thermal fuse designs that require high breaking capacity.

工作溫度範圍:
SF type is 73 °C ~ 240 攝氏度, SM type is 76 °C ~ 187 攝氏度. There are various products with a rated current of 0.5A to 15A. Safety certifications include: UL認證, CSA （英語：CSA）, VDE, BEBA, PSE, JET, CQC質素控制 … 證書. Comply with EU ROHS environmental protection directive requirements. NEC temperature fuse has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rises of household or industrial electrical products and quickly and timely cut off the circuit, which can prevent the fire from being unburned.
NEC thermal fuse is a component that provides very reliable protection in over-temperature conditions. It has small volume, large overcurrent, non-reset, stable performance, convenient installation, and has a range of humidity settings and carrying capacity to choose from to meet customer application requirements.
Products are widely used in:
Various motors, copiers, fax machines, HID ballasts, fluorescent lighting ballasts, 變形金剛, 充電器, battery packs, heating appliances, electric irons, hot air blowers, electric stoves, 電飯煲, 電熱水壺, 咖啡機, Ventilation fans, electric fans, electric sewing machines, 熱水器, power converters, power plug sockets, 雪櫃, 空調, automotive air conditioners, meters, equipment, 等. are over-temperature protected.
