LEU, COLORANT, Panasonic, Siguranță termică SWC Limiter

The fuse materials used in LEAO, COLORANT, Panasonic, 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.

Materialul topit folosit în LEAO, COLORANT, Panasonic, Siguranțele termice SWC joacă un rol vital în performanța siguranțelor termice și sunt una dintre componentele de bază ale întregului dispozitiv.. După caracteristicile materialului topit, le putem împărți în două categorii: punct de topire scăzut și punct de topire ridicat. 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. On the other hand, 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. In addition, 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.

Operating temperature range:
SF type is 73 ℃ ~ 240 ℃, SM type is 76 ℃ ~ 187 ℃. There are various products with a rated current of 0.5A to 15A. Safety certifications include: UL, CSA, VDE, BEBELUS, PSE, AVION, CQC … certificates. Comply with EU ROHS environmental protection directive requirements. NEC temperature fuse has the function of detecting abnormal temperature and cutting off the circuit. Poate detecta creșterile anormale de temperatură ale produselor electrice de uz casnic sau industrial și poate întrerupe rapid și în timp util circuitul, care poate preveni ca focul să fie nears.
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.
