Eaton Specification Sheet - DFJ-90-W
High-speed fault interruption with a 90 A rating delivers immediate protection in energized equipment. By interrupting faults before fault energy accumulates, equipment damage, arc flash risk, and downtime are significantly reduced, yielding lower maintenance costs and improved mean time between failures. Application: Ideal for motor drives, programmable logic controllers, and power distribution panels in industrial automation; the 200 kAIC interrupt rating at 600 Vac ensures resilience against high-energy faults. clip-lock connection and melamine tube enable quick replacements and reliable insulation, reducing maintenance time and prolonging panel life. Comprehensive certifications simplify audits and procurement while CE marking and UL/CSA listings validate safety and compliance across global facilities. The compact 4.83 in length, 1.19 in height, and 1.18 in width footprint suits space-constrained panels without sacrificing performance. Compatibility with Bussmann series reduces training needs and accelerates retrofits across plants.

FAQs
DFJ-90-W uses a clip-lock connection designed for quick field replacement without special tools. Ensure the clip-lock terminals mate with standard Bussmann-series clips in Class J fuse holders, maintain proper alignment to avoid arcing, and verify secure seating to preserve interrupt performance under load. The Melamine tube provides insulation for safe operation in typical industrial cabinets.
The DFJ-90-W is rated for 90 A with an interrupt rating of 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc. Voltage rating is 600 Vac or less and 450 Vdc or less, making it suitable for a wide range of industrial power circuits. It is a Class J, non-indicating fuse with a Melamine tube construction.
Yes. With a 90 A rating and high interrupt capacity, the DFJ-90-W is well-suited for motor drives and automation controls where rapid fault clearing protects drives, cables, and power electronics. Its clip-lock design simplifies maintenance, and its compact form factor helps fit into dense control panels typical of conveyors and packaging lines.
DFJ-90-W carries CE marking and RoHS compliance, along with CSA certification and UL listing. These certifications validate safety, environmental compliance, and third-party reliability, facilitating cross-border procurement and reducing qualification time in regulated industries such as food processing, packaging, and material handling.
Using the DFJ-90-W can reduce downtime from short circuits due to its fast interruption (high AIC ratings), lower maintenance costs through quicker replacements with clip-lock design, and simplify spares management with a standard Bussmann-series fuse footprint. Combined, these factors shorten mean time between outages and improve overall line productivity.
