JKS Fast-Acting Fuses

Marshall E. Campbell Co is your source for inventory and know-how. Our team will save you time and help increase productivity with the fast-acting fuse you need. Shop your JKS fast-acting fuses with MEC Co. JKS fast-acting fuses open circuits quickly when surges are detected. More compact than UL Class RK1 or RK5 fuses, they are suitable for tight spaces. Use with Fuse Blocks for UL Class J Fuses. Fast-acting, curent-limiting fuses are available in ratings from 70 to 600 amps. Fast-acting fuse helps prevent equipment damage caused by short-circuit events. Ideal for critical industrial or commercial applications that have specific current limitation requirements.
