Eaton JKS-600 Fuse - 200 kAIC at 600 Vac
Part Number: JKS-600
Quick Summary
Eaton JKS-600 fuse is a fast-acting protection device that guards electrical circuits in industrial power systems. When service feeders demand reliable fault clearance, engineers need a device that won’t compromise uptime. With RoHS compliance and Class J characteristics, the JKS-600 balances fast response with safe, compliant operation. Designed for 600 V systems and 600 A ratings, it delivers a 200 kAIC interrupt rating at 600 Vac, helping protect equipment and reduce downstream damage. This makes it well suited for motor drives, control panels, and high-current feeders in manufacturing and process industries. Its standard form factor with bolted blade ends simplifies installation in existing Bussmann series cabinets and minimizes retrofit time.

Bussmann series JKS fast-acting Class J fuses, 70-600A technical data sheet no. 1027
The JKS-600 fuse combines high current capability with precise coordination for power distribution protection. Feature → Business Impact → Application: The 600 A amperage rating with a 600 V rating provides robust protection for mid- to high-current circuits, enabling reliable fault clearance and reducing downtime, especially in motor control centers and line feeders. In practice, this translates to fewer unplanned outages and lower risk of equipment damage during fault conditions in manufacturing environments. The 200 kAIC interrupt rating at 600 Vac ensures the fuse can safely interrupt high fault currents seen in industrial systems, safeguarding downstream equipment and extending panel life in process facilities. Application-wise, this supports fast-acting coordination in control panels, drives, and feeder cabinets, with long-term savings from reduced arc energy and safer maintenance. The bolted blade end connections offer proven compatibility with standard Bussmann series cabinets, enabling straightforward retrofits and scalable protection as line loads grow. This design also facilitates installation in tight spaces, minimizing wiring complexity and commissioning time. RoHS compliance reduces regulatory risk and enhances supplier eligibility across OEMs, distributors, and global installations. Compatibility with existing protection schemes and the Class J fast-acting profile makes this fuse a reliable, cost-effective option for industrial power distribution.

FAQs
Yes. The JKS-600 uses bolted blade end connections designed for standard Bussmann series fuse blocks. Ensure the panel has compatible blade contacts and space for an 8 in long, 2.5 in wide, 2.5 in high unit. Refer to the Bussmann technical data sheet no. 1027 for torque and wiring guidelines; this minimizes installation risk.
Key specs include 600 A amperage rating, 600 V voltage rating, and a 200 kAIC interrupt rating at 600 Vac. As a fast-acting, current-limiting Class J fuse, it delivers rapid fault interruption, reducing damage to motors and drives and helping meet electrical codes in industrial facilities in diverse climates and panel configurations.
Yes, the JKS-600 is RoHS compliant, aligning with modern regulatory expectations. Its Class J, fast-acting design suits manufacturing, process industries, and energy sectors where reliable protection, reduced downtime, and compliant sourcing are critical. It integrates with standard power circuits, helps meet NEC/UL frameworks, and supports RoHS-based supply chains across OEMs and distributors across global installations.
Because it is a non-indicating fuse with a robust Class J design, the JKS-600 requires periodic inspection for continuity and contact integrity in high-current circuits. The 8 in length and bolted blade ends support secure, reusable mounting in service cabinets. Use the official Bussmann data sheet for recommended replacement intervals.
High interrupt capability and fast-acting response reduce damage to downstream equipment, lowering maintenance costs and downtime. The RoHS compliance streamlines procurement and reduces regulatory risk, while the standard packaging and widespread compatibility minimize retrofit time in existing panels, delivering a favorable return on investment through longer mean time between failures.
