Eaton JJN-2 Fuse - 200 kAIC at 300 Vac Class T
Part Number: JJN-2
Quick Summary
The Eaton JJN-2 fuse protects electrical circuits in distribution panels and multi-family metering where fast, current-limiting protection is essential. Engineers face nuisance trips and selecting a device that balances short-circuit endurance with real-world inrush demands. This solution carries CE marking and RoHS compliance for broad regulatory alignment, and it belongs to the Class T family for reliable, fast-acting protection. With a compact footprint and standard packaging, it fits common fuse blocks and space-constrained panels. The 2 A rating and 200 kAIC interrupt capability at 300 V deliver robust fault mitigation while keeping maintenance costs predictable. In practice, it supports VFD line protection and metering stacks without compromising uptime.

FAQs
The JJN-2 is a Bussmann series cartridge-style fuse designed to fit standard low-voltage branch circuit fuse holders used in Eaton Bussmann installs. With a compact footprint (0.88 in x 0.41 in x 0.41 in) and a standard packaging format, it integrates smoothly into existing panel layouts and meter stacks without requiring adapters. Always verify holder type and slot size against the catalog specification before replacement.
JJN-2 is a 2 A current-limiting fuse from the Bussmann Class T family with an interrupt rating of 200 kAIC at 300 Vac. It is rated for 300 V and features non-indicating status. The fuse is packaged standard, with dimensions of 0.88 in length and 0.41 in width/height, and ships in a 10-unit quantity. These specs support protective performance in VFD lines and distribution panels.
Yes. The JJN-2’s 2 A rating, high interrupt capacity, and current-limiting behavior make it well-suited for VFD line protection and metering stacks in large residential complexes. Its Class T fast-acting design helps mitigate motor-driven inrush without excessive nuisance trips, preserving uptime and extending downstream equipment life in multi-family installations.
The JJN-2 carries CE marking and RoHS compliance, indicating conformity with European safety and environmental standards. This helps with global procurement and regulatory alignment for electrical protection devices used in commercial and residential applications.
JJN-2 provides predictable lifecycle costs through standard packaging (10 units per package) and a compact form factor that simplifies stocking and field replacement. Its reliable current-limiting performance reduces downtime from faults, protecting valuable loads like motors and meters, and supports a clear ROI through reduced maintenance intervals and faster service restoration.
