Glass Tube Fuse 5*20 125V/150V Fast-Acting RF1-20/125V/150vseries
Model No.: RF1-20/125V/150Vseries
RF1-20 (H) ceramic tube high breaking fast-acting fuse, with size: Ф5×20±0.5, the products conform to TUVJ50078894 standard. This product is not with lead, and needs to be fitted with a holder or clip.
This product is: fuse installed in the porcelain tube is filled with quartz sand, which acts as the arc extinguishing medium. The particle size of quartz sand has a great influence on the arc extinguishing performance, and the particle diameter is in the range of 0.2~0.3mm. When the overload current or short-circuit current goes through the fuse, the fuse melts and arc is generated in the tube, the quartz sand has a strong cooling effect on arc and deionization, the arc soon extinguished. In breaking up the large short-circuit current; usually the arc can be extinguished before the short circuit current has not reached the maximum value. In the whole process of breaking current, there is the phenomenon of silent light, no ionized gas, and high breaking capacity.
