Class RK5 Time-Delay Fuses
Marshall E. Campbell Co makes it easy to find and buy the right RK5 fuse for your next electrical project. With a large inventory of Bussmann fuses with a focus on amperage, voltage, and diameter, MEC provides you with the tools you need to get the job done. RK5, also known as dual-element fuses, these time-delay fuses withstand current overload for a short time so they won't open when exposed to harmless temporary surges. Can size them close to 125% of motor FLA while providing excellent short circuit protection. They have a rejection-style end design that safeguards against replacement errors. Fuse indication option available on select ratings. Fits Bussman class R fuse blocks. Helps protect motors against burnout from single-phasing on three-phase systems.
