Description: High-speed fuses are different from standard fuses. One main difference is the configuration. A high-speed fuse comes with a reduced section, providing you with quick opening and clearing. It can also withstand higher operating temperatures since it is made from a more premium grade material with better thermal conductivity. High-speed fuses are often utilized with semi-conductors like transistors and diodes since they are suitable for higher temperature operations. For circuit protection and distribution tools and parts like fuses, MRO Supply has them. Our Bussmann fuse selection consists of high-grade standard and high-speed fuses in varying ratings. Shop now.
