Eaton JJN-30 Fuse - Class T, 30 A, 20 kAIC at 160 Vdc
Part Number: JJN-30
Quick Summary
The Eaton JJN-30 fuse is a current-limiting device designed for motor drives and VFD line protection. Engineers often struggle with nuisance trips and undersized protection when wiring variable-speed drives. CE marking and RoHS compliance ensure regulatory alignment, while Class T fast-acting protection suits demanding loads. Combined with ferrule-end connections and standard packaging, the JJN-30 delivers reliable protection with straightforward installation. This enables shorter downtime and simpler inventory management for panel builders and end users. With a 30 A rating and high interrupt capabilities, it protects VFD lines against fault currents without excessive nuisance tripping. This combination translates into predictable performance, safer equipment, and improved maintenance planning.

FAQs
The JJN-30 uses ferrule-end terminations, enabling quick, secure crimps with standard tooling. Ensure correct torque and crimp specifications for ferrule terminals, confirm compatible fuse holders, and provide adequate clearance for replacement. Use appropriate crimp sleeves and conductors sized for 30 A to maintain reliable current rating and minimize contact resistance over time.
JJN-30 is a current-limiting Class T fuse designed for VFD line protection, delivering fast clearing of fault currents. It provides 30 A rated current with 20 kAIC at 160 Vdc and up to 200 kAIC at 300 VAC, ensuring safe interruption for high-inrush conditions typical in motor drives, while limiting arc energy and protecting upstream equipment.
Yes. The ferrule-end design and standard packaging make JJN-30 compatible with common Bussmann series fuse holders and panel designs. Its ferrule-end terminations provide straightforward integration with existing wiring harnesses, reducing modification needs and supporting consistent electrical characteristics across the protection scheme.
JJN-30 is CE marked and RoHS compliant, aligning with European safety and environmental requirements. Class T fuses are recognized for fast-acting protection in motor drive circuits; confirm any local UL/CSA requirements with the panel manufacturer, as those listings are not specified in the data provided and may require additional certification depending on the region.
Using JJN-30 can reduce downtime by preventing extended fault events and limiting arc damage to drives and contactors. Its reliable, non-indicating design minimizes maintenance checks while ensuring robust Vin protection. The result is lower replacement costs, simpler spare parts management, and improved overall asset uptime in production lines.
