Eaton JJN-60LS Fuse - Class T Current-Limiting
Part Number: JJN-60LS
Quick Summary
JJN-60LS fuse from Eaton Bussmann series delivers reliable current-limiting protection for building feeders and VFD supply lines. In large projects, engineers struggle to balance fast fault clearing with selective coordination and minimal nuisance blows. This device offers a Class T fuse with non-indicating operation and RoHS compliance, simplifying maintenance and sourcing. Its compact footprint supports dense panel layouts, while Eaton’s engineering data helps ensure you select the right coordination with upstream devices. The result is improved reliability, reduced downtime, and clearer budgeting for protective devices across multi-family and commercial installations. Secondary value comes from broad catalog compatibility and straightforward stocking for procurement teams.

Feature: Current-limiting, 60 A, Class T construction. Benefit: Limits fault current and protects downstream equipment, reducing damage and downtime in demanding power environments. Application: VFD line protection and feeder protection in large buildings; supports selective coordination with upstream breakers and meters. Feature: Compact dimensions (0.88 in L x 0.56 in W x 0.56 in H) and standard packaging. Benefit: Easier panel density, faster retrofits, and simplified replacement in existing Bussmann catalog ecosystems. Application: Space-constrained panels in multi-family housing and commercial facilities; compatible with standard fuse holders and Bussmann catalogs for efficient stocking. Feature: RoHS compliant and non-indicating. Benefit: Supports sustainable manufacturing and low-maintenance operation; avoids visual indicators that could confuse status in busy panels. Application: High-visibility layouts and compliance-driven projects in regulated markets. Feature: 60 A rating with non-indicating, fast-acting protection. Benefit: Quick fault isolation reduces arc flash exposure and equipment wear, improving maintenance intervals. Application: motor drives, chiller systems, and other high-inrush loads in large complexes. Feature: Standard packaging and catalog compatibility. Benefit: Streamlined procurement and consistent spare parts strategy across projects. Application: Multi-site deployments requiring uniform protection across facilities.

FAQs
The JJN-60LS is designed to fit standard Bussmann/MOD fuse holders used in Class T protection schemes. Its 0.88 in length and 0.56 in cross-section align with common panel mount geometries, enabling straightforward replacement in existing installations without modifying bus bars or mounting hardware. When selecting holders, verify compatibility with non-indicating, 60 A current-limiting fuses and follow Eaton storage recommendations for spare parts.
The JJN-60LS is a 60 A current-limiting, fast-acting fuse in the Class T category. It constrains short-circuit currents rapidly to protect downstream equipment and wiring, reducing arc energy and thermal stress. This coordination supports selective protection schemes, minimizes nuisance tripping in high-inrush environments, and improves overall system reliability in protected feeder circuits.
Yes. The JJN-60LS is well-suited for VFD line protection and feeder protection in large apartment complexes and multi-family installations. Its current-limiting 60 A rating, non-indicating design, and Class T construction provide fast fault clearing while preserving upstream coordination. Its RoHS compliance and compact form factor further simplify integration into dense panel layouts and compliance-driven projects.
The JJN-60LS carries RoHS compliance as indicated in its general specifications. It is a Class T, non-indicating fuse designed for current-limiting protection. While other certifications aren’t listed in the available data, RoHS compliance ensures restricted use of hazardous substances, aligning with sustainability goals and universal compliance practices in many markets.
Using the JJN-60LS can lower maintenance costs by reducing frequent nuisance trips and minimizing downstream damage from short circuits. Its compact size eases replacement, stocking becomes standardized through the Bussmann catalog, and the 60 A current-limiting design shortens fault duration, contributing to higher equipment availability and a lower total cost of ownership for protective systems in large facilities.
