Eaton JKS-200 Fuse - Class J, 200 kAIC at 600V
Part Number: JKS-200
Quick Summary
The Eaton Bussmann JKS fuse provides fast-acting Class J protection for 200 A industrial power circuits. Nuisance trips and slow fault isolation in control panels and motor circuits challenge uptime and maintenance budgets. RoHS compliant and part of the Bussmann Class J family help ensure regulatory alignment and dependable performance in harsh environments. Designed for bolted blade connections, the JKS integrates easily into standard electrical protection schemes, delivering reliable interrupting capability at 600 V. This arrangement supports safer, more efficient panel designs and reduces total cost of ownership for electrical protection and circuit control. Its compact form also enables rapid field replacements within scalable protection schemes.

Bussmann series JKS fast-acting Class J fuses, 70-600A technical data sheet no. 1027
Feature: The JKS fuse delivers fast-acting Class J protection with a 200 A rating and current-limiting behavior. Impact: This minimizes fault energy and protects costly drives, contactors, and wiring during short circuits, reducing downtime and repair costs. Application: Suitable for motor control centers, feeders, and panelboards where reliable protection is essential in harsh industrial environments. Feature: With a 200 kAIC interrupt rating at 600 Vac, the JKS quickly interrupts high-energy faults. Impact: This capability lowers arc flash exposure, minimizes collateral damage, and keeps critical lines energized for longer uptime. Application: Power feeds to motors, drives, and equipment in manufacturing cells requiring robust fault clearing. Feature: Rejection style and bolted blade end connections ensure correct orientation and secure seating. Impact: Eliminates misinstallation risk and ensures predictable, safe operation during high-energy faults. Application: Installation in standard Bussmann-style holders and panel boards across industrial settings. Feature: RoHS compliant construction supports regulatory compliance and sustainable manufacturing practices. Impact: Reduces compliance risk and supports green, responsible electrical design. Application: Global deployments where RoHS requirements apply, including European and North American facilities. Feature: Compact footprint and single-element design simplify retrofits and serviceability. Impact: Facilitates easier upgrades, faster replacements, and compatibility with existing Bussmann JKS family components. Application: Panel modernization projects and new equipment builds where space is at a premium.

FAQs
The JKS-200 provides fast-acting Class J protection with a 200 A rating and current-limiting behavior, designed to limit fault energy and protect motors, drives, and wiring during short circuits. Its 600 Vac rating and high interrupt capacity support reliable fault clearing in motor control centers and feeder circuits, reducing downtime and extending equipment life.
A 200 kAIC interrupt rating at 600 Vac ensures high-energy faults are cleared quickly, minimizing arc energy and collateral damage. This improves safety for personnel, reduces the likelihood of cascading faults, and increases overall system uptime by keeping critical feeders energized while protecting downstream equipment.
Yes, the JKS-200 is RoHS compliant. This means it meets restrictions on hazardous substances, aiding regulatory compliance in global installations, supporting sustainable design goals, and simplifying procurement for projects requiring RoHS adherence across diverse markets.
When replacing fuses with JKS-200, ensure compatibility with bolted blade end connections and verify the physical fit within the panel space. Check the single-element design and the standard packaging for straightforward replacement. Confirm voltage and current ratings match the circuit requirements and coordinate with upstream protection for proper fault clearance levels.
The JKS-200 is a fast-acting, single-element fuse with a non-indicating design, intended for reliable protection rather than ongoing indication. In production environments, plan for periodic inspection of panel connections, verify torque on bolted blades, and maintain coordination with upstream protection to ensure predictable fault clearing and minimal equipment wear over time.
