Bussmann NSB JKS-225 Fuse

Bussmann JKS-225 is a Class J fast-acting, current-limiting fuse from Eaton’s Bussmann Series (LIMITRON) designed for bolted, single-barrel installations. It is rated for 225 A at 600 V AC, with a 200 kA interrupting rating at 600 V, and is built as a rejection-style, non-indicating fuse with bolt-on ends. This 1-barrel, 2.11-inch-diameter fuse is commonly specified for UL low-voltage applications and is used to protect power panelboards and machinery by quickly opening on overcurrent events while minimizing damage to upstream circuitry. The JKS-225 belongs to the JKS family of fuses and is described in distributor and catalog listings as a fast-acting, current-limiting device suitable for 600 V circuits, making it a solid choice for industrial control panels, motor protection, and other high-current applications where reliable, high-current protection is required. In summary, the JKS-225 provides robust Class J protection with a proven 225 A, 600 V specification, a 200 kAIC rating, bolt-on assembly, and a non-indicating, rejection-style design that suits demanding power distribution and machinery protection tasks.
