Eaton JJN-80 Fuse - Class T, 80 A, 300 Vac
Part Number: JJN-80
Quick Summary
The Eaton JJN-80 fuse is a current-limiting protection device designed for high‑demand motor drives and VFD circuits. Engineers frequently battle nuisance trips during transient events and struggle to source compact, compliant protection for tight electrical layouts. This fuse is CE marked and RoHS compliant, with Class T performance delivering reliable protection for motor drives and power conversion systems. By pairing an 80 A rating with bolted blade ends and high interrupt capability, it supports safer installations, simpler maintenance, and lower total cost of ownership in industrial automation environments. Its compatibility with Bussmann series line protectors helps harmonize protection schemes across panels and machines.

JJN-100~TRON FAST ACTING FUSE CLASS T
Feature: Current-limiting action quickly confines arc energy, protecting downstream components and reducing fault cascade. Business Impact: Shortens outage times, extends motor drive life, lowers maintenance costs. Application: Suitable for VFD line protection in conveyor systems and packaging machinery. Feature: Class T fuse construction offers precise time-current coordination with protecting devices. Business Impact: Improves selectivity, preventing unnecessary tripping of upstream breakers. Application: Ideal for control panels where predictable fuse behavior matters. Feature: 20 kAIC at 160 Vdc and 200 kAIC at 300 Vac interrupt ratings give strong protection across DC and AC circuits. Business Impact: Reduces risk of catastrophic damage during short circuits and transient faults. Application: Best for mixed loads in drive systems and DC link protection. Feature: Bolted blade end x bolted blade end and non-indicating design simplify field installation and status checks. Business Impact: Speeds commissioning and minimizes mis-wiring and maintenance headaches. Application: Bolt-in installation in OEM and retrofit panels. Feature: Standard packaging with 5 pieces per pack; CE marked and RoHS compliant. Business Impact: Streamlines procurement, global compliance, and reduces LOP inventory. Application: Panel builders and contractors deploying Bussmann series fuses. Feature: Compatible with Eaton Bussmann series fuse family; 80 A rating fits common motor drive protections. Business Impact: Enables scalable protection architecture and easier spare part strategy. Application: Carried in electrical protection inventories for manufacturing facilities.

FAQs
The JJN-80 uses bolted blade end connections, simplifying field wiring by allowing direct bolting into standard fuse holders or panel buses. Use a torque-per-spec connection to ensure secure contact, verify alignment, and replace only with identical Class T devices to maintain system coordination.
Key specs include an 80 A amperage rating, 300 Vac and 160 Vdc voltage ratings, and interrupt ratings of 200 kAIC at 300 Vac and 20 kAIC at 160 Vdc. Non-indicating, standard packaging of five pieces per pack and Class T construction support predictable protection in motor drive circuits.
Yes. The JJN-80 is designed for VFD line protection, featuring current-limiting action and high interrupt capabilities to protect motor drives and power conversion panels, while providing reliable selectivity with Class T coordination.
The JJN-80 is CE marked and RoHS compliant, meeting European safety and environmental requirements. This ensures suitability for global deployments, reduces compliance risk, and supports connector and enclosure coordination with other Bussmann-series protections.
The JJN-80’s standard 5‑piece packaging, compatibility with the Bussmann fuse family, and high interrupt ratings reduce maintenance time, spare-part complexity, and downtime during protection upgrades, delivering faster commissioning and a lower total cost of ownership across multiple sites.
