Industrial NSB JKS-600 Fuses

The JKS-600 is Eaton Bussmann’s Limitron series fast-acting cartridge fuse designed for bolted-mount installation in high‑current electrical assemblies. It is rated for 600 A at up to 600 V AC and uses bolt-end terminals in a cylindrical body measuring 2.500 inches in diameter by 3.750 inches long, with a 200 kA interrupting rating at the rated voltage. As part of the Limitron JKS family, the fuse provides rapid overcurrent protection for demanding power‑distribution applications, and it carries UL, CSA, and CE approvals. Commonly used in power panelboards and machinery disconnects, the JKS-600 is suited to protect feeders and large loads where a 600 A, 600 V class‑J fuse is required, aligning with Bussmann’s Class J form factor for compatible enclosures and holders in industrial control setups.
