Eaton JJN-1 Fuse - Class T, 200 kAIC at 300 VAC
Part Number: JJN-1
Quick Summary
The Eaton JJN-1 fuse provides current-limiting protection for 1 A circuits in commercial and multi-family electrical systems. Engineers often wrestle with selecting fuses that meet high interrupt ratings while minimizing nuisance trips and downtime. This model is CE marked and RoHS compliant, ensuring regulatory alignment and safer, more sustainable installations. Designed for reliability in large apartment complexes and multi-family meter stacks, it delivers VFD line protection and dependable short-circuit interruption, reducing repair windows and site visits. By choosing a Class T, non-indicating fuse with a 200 kAIC at 300 V rating, you gain targeted protection for critical loads while improving maintenance planning and total cost of ownership.

JJN-100~TRON FAST ACTING FUSE CLASS T
Feature → 1 A current-limiting protection reduces fault energy and minimizes arc flash risk, protecting conductors and switchgear. This directly lowers thermal stress on cables and downstream devices, translating into longer component life and fewer nuisance trips that disrupt critical loads. It’s well-suited for 1 A protection in commercial panels and multi-family meter stacks, delivering predictable performance where space is limited. Feature → 200 kAIC interrupt rating at 300 VAC provides a substantial protection margin for short circuits and motor drives. The Class T fast-acting design balances selective coordination with rapid clearing, minimizing downstream damage and downtime. This configuration is particularly well-suited for VFD line protection and other sensitive loads in distribution panels. Feature → CE marking and RoHS compliance ensure regulatory and sustainability goals are met. The fuse uses a compact 0.88 in length, 0.41 in width, and 0.41 in height form factor that fits standard fuse clips. It ships in standard packaging (10 pieces) for quick replenishment, reducing stocking complexity and procurement cycle times. Feature → Non-indicating status reduces panel clutter and simplifies preventive maintenance, while remaining visible through field-proven indicators. Combined with a standard packaging type, 10 pieces per package, and a lightweight 0.1 lb weight, installers gain efficient replacements and predictable lead times. Feature → The JJN-1’s compatibility with standard Bussmann JJN holders and its compact footprint support easy installation in existing panels, minimizing retrofit risk and enabling fast disruption-free upgrades.

FAQs
JJN-1 is designed for standard Bussmann JJN fuse holders used in commercial and multi-family installations. Its 0.88 inch length and 0.41 inch width fit typical clip spacing, while the standard packaging of ten units supports quick stocking. Always verify your panel’s clip type and catalog number JJN-1 to ensure proper fit and consistent replacement timing.
Key ratings include a 1 A amperage rating, a 200 kAIC interrupt rating at 300 VAC, and a 300 V voltage rating. The device uses a Class T fast-acting design and is non-indicating, which helps reduce panel clutter while delivering reliable protection for circuits feeding motors and drives.
Yes. The JJN-1 provides a high interrupt rating of 200 kAIC at 300 VAC and current-limiting action, which minimizes fault energy and nuisance trips on variable-frequency drives. Its compact form factor also simplifies installation in constrained panel spaces typically found near drives and motorized equipment.
The JJN-1 fuse is CE marked and RoHS compliant, supporting European regulatory requirements and environmental standards. If your project requires additional approvals (such as UL listings), confirm compatibility with your panel and local regulations before procurement.
Using JJN-1 can lower maintenance costs by reducing downtime due to nuisance trips and enabling faster replacements with its standard 10-unit packaging. The compact, lightweight design minimizes handling, while the high interrupt rating provides protection margins that reduce downstream repair expenses over the system lifecycle.
