Product Description
The Eaton Bussmann JKS-90 is a 90 Amp, 600 Volt AC, Class J cartridge fuse — part of the JKS Limitron ™ line. Designed as a fast-acting, current-limiting fuse, it provides robust over-current and short-circuit protection in high-fault-current electrical systems. With a 200-kA interrupt rating, this fuse is built to safely clear faults while protecting wiring, equipment, and circuits — ideal for power panelboards, machinery disconnects, feeders, and industrial control systems.
