Eaton JJS-1 Fuse - Class T, 600V, 200 kAIC RoHS
Part Number: JJS-1
Quick Summary
JJS-1 fuse from Eaton delivers precise current-limiting protection for 600 V drives and control circuits. Engineers often wrestle with nuisance fuse blows in VFD-rich environments and tight enclosures; this compact Class T device minimizes that risk while saving valuable space. It features a current-limiting, very fast-acting design that clears faults quickly, reducing downstream heat and arc exposure. The JJS-1 carries a 200 kAIC interrupt rating at 600 V and is CE marked with RoHS compliance, supporting global safety and regulatory requirements. With a 1 A rating and ferrule-end connections, installation is straightforward and stocking is simpler for maintenance teams. The small footprint helps maintain IEC/UL compatibility while delivering dependable protection for motor drives and control panels.

FAQs
The JJS-1 uses ferrule-end terminations that require standard crimping tools and proper torque on ferrules to ensure secure, vibration-resistant connections. Mounting should maintain adequate clearance for heat dissipation and follow OEM enclosure guidelines. Verify compatibility with standard DIN-rail or panel-mill mounting as applicable and reference Eaton data sheets for recommended torque values.
A 200 kAIC interrupt rating means the fuse can safely interrupt high fault currents without catastrophic failure, protecting downstream components like drives, contactors, and wiring. This rating supports robust protection for motor drive startups and short-circuit events, reducing the risk of collateral damage and improving overall system reliability in high-energy applications.
Yes. The JJS-1 is a current-limiting, fast-acting Class T fuse designed for 600 V systems and VFD line protection. Its 1 A rating and 200 kAIC interrupt capability make it well-suited to protect drives, power supplies, and control panels from overloads while minimizing nuisance blows in demanding motor-drive environments.
The JJS-1 is CE marked and RoHS compliant, signaling adherence to EU safety, health, and environmental requirements. These certifications help ensure regulatory alignment for global deployments, facilitate supplier qualification, and support compliance audits in manufacturing facilities and international supply chains.
The JJS-1 is packaged standard, with 10 units per pack, enabling economical stocking for service needs and project builds. Standard packaging simplifies reorder points, reduces inventory complexity, and supports predictable lead times in maintenance depots and production lines.
