Overview
The Eaton Bussmann JKS-5 Limitron Class J fuse delivers fast-acting, current-limiting protection for industrial and commercial electrical circuits. Rated for 5 amperes at 600 volts AC, this fuse features a 200 kA interrupting rating at 600 Vac and meets UL Standard 248-8 for branch circuit protection. The JKS-5 is a single-element, rejection-style fuse designed for selective coordination in power distribution systems and control panels.

- Lighting and heating circuits requiring fast overcurrent response
- Control circuits in plants, manufacturing facilities, and commercial buildings
- Protection of circuits with low interrupting capacity breakers
Compatibility & Replacements
Compatible With
- Class J fuse blocks and holders with rejection-style openings
- Industrial power distribution systems rated up to 600 V AC
- Control panel designs using UL Standard 248-8 fuses
- Eaton Bussmann power distribution fuse blocks (PDFB) for Class J ferrule fuses
Replaces / Drop-In Replacement For
The JKS-5 directly replaces other Limitron JKS series 5A, 600V fast-acting fuses from Eaton Bussmann. Verify compatibility with your existing fuse holders before ordering, as Class J fuses use a rejection-style design that prevents installation in incompatible blocks.
