Eaton Specification Sheet - DFJ-17.5
Feature → Business Impact → Application: The DFJ-17.5’s Class J, high-speed design delivers precise short-circuit interruption, reducing arc flash exposure and enabling tighter protection coordination in motor drives and control panels. This directly translates to fewer nuisance trips and longer equipment life, saving maintenance time and spare parts costs in high-volume manufacturing cells. Application: motor drives, CNC machines, and automated assembly lines where fast fault clearance protects costly loads. Feature → Business Impact → Application: 17.50A rating with 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc ensures robust protection across mixed AC/DC circuits, improving selectivity and limiting fault propagation. Application: cross-voltage protection schemes in automation cabinets. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections enable quick, reliable terminations in panel boards, reducing installation time and tightening vibration resistance in rugged environments. Application: service panels and field retrofit projects. Feature → Business Impact → Application: Non-indicating design minimizes maintenance points and simplifies replacement in high-density layouts, while the melamine tube provides chemical resistance and durability. Application: hazardous or space-constrained control panels. Feature → Business Impact → Application: Compliance with CE Mark, RoHS, CSA, and UL supports global manufacturing standards, easing supplier qualification and audit readiness. Application: multinational facilities, OEM builds, and regulated industries.

FAQs
Install by confirming the panel is within 600 Vac or 450 Vdc ratings and that ferrule-end conductors are compatible with Class J devices. Use ferrule-end x ferrule-end terminations and follow standard safety procedures. Ensure the fuse aligns correctly with the holder, then secure without over-tightening to maintain reliable contact and vibration resistance.
The DFJ-17.5 provides a 17.50A rating, with an interrupt rating of 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc. It is rated for 600 Vac or less and 450 Vdc or less, Class J, with ferrule-end connections and a melamine tube, designed for high-speed fault clearing.
Yes. The device accommodates 600 Vac or less and 450 Vdc or less, with an interrupt rating that supports robust protection for mixed AC/DC motor drive and control circuits, making it suitable for a wide range of industrial applications.
Yes. The DFJ-17.5 carries CE marking and RoHS compliance, and is CSA Certified and UL Listed, providing broad regulatory acceptance for global manufacturing and installation in compliant environments.
Non-indicating fuses reduce potential failure points and simplify visual inspection in tight panel layouts. Combined with a reliable 17.50A rating and high interrupt capability, this can lower maintenance time and spare-part inventory while improving uptime in automated lines.
