Eaton JKS-5 Fuse - Class J 200 kAIC at 600 Vac
Part Number: JKS-5
Quick Summary
The Eaton JKS-5 fuse is a fast-acting Class J protection device designed for industrial power circuits. Engineers often contend with nuisance trips from surges and inrush, and the JKS-5 mitigates this with precise current-limiting response. CE marking and RoHS compliance accompany its 600 V rating and 200 kAIC interrupt capacity, enabling safe, regulator-friendly integration in European and global equipment. As part of the Bussmann series, it aligns with standard ferrule-end Class J fuses, simplifying stocking and maintenance. Its compact 0.81 in by 0.81 in cross-section and 2.25 in height fit many enclosures, delivering reliable protection for critical loads while supporting streamlined procurement and service routines.

FAQs
Install the JKS-5 with ferrule-end connections as specified, ensuring the fuse fits the Class J footprint and that the enclosure supports 600 V operation. Confirm the circuit is de-energized, insert until seated, and verify the ferrule ends are fully crimped for reliable contact and current interruption. This reduces the risk of hot spots and premature failure in motor control circuits.
Yes. The JKS-5 adheres to the Bussmann Series Class J standard with ferrule-end connections, allowing straightforward substitution within compatible panel ranges and ensuring consistent mounting, electrical contact, and protection characteristics across the fleet of Class J fuses.
The JKS-5 is ideal for industrial control panels, motor control circuits, and power supplies that require fast-acting protection and a 200 kAIC interrupt rating at 600 Vac. Its 5 A rating makes it suitable for small to medium load circuits where precise coordination reduces nuisance trips.
The JKS-5 is CE marked and RoHS compliant, aligning with European regulatory requirements. Its 600 V rating and current-limiting, fast-acting behavior meet common electrical protection standards for safety, reliability, and environmental compliance in modern industrial facilities.
With its high interrupt rating and current-limiting performance, the JKS-5 reduces downstream damage and maintenance downtime, improving line uptime. Standardized, ferrule-end design supports easy replacement, inventory consolidation, and faster technician replacement cycles, delivering tangible operating savings over time.
