FAQs
DFJ-500 installs quickly through a clip-lock connection compatible with Class J fuse holders, and it ships in a standard packaging format for easy stocking. The Melamine tube contributes to robustness while the overall footprint (8.28 in L × 2.71 in W × 2.65 in H) fits most control panels. The secure clip-lock interface minimizes wiring errors and reduces field labor during replacement.
DFJ-500 provides a 500 A amperage rating with a 200 kAIC interrupt rating at 600 Vac and 100 kAIC at 450 Vdc, enabling fast fault clearance for high-energy circuits. Its voltage rating is 600 Vac or less and 450 Vdc or less, aligning with standard industrial controls. This means robust protection against short circuits while supporting safe selective coordination in multi-fuse schemes.
Industries with demanding motor control and drive applications benefit most, including manufacturing automation, packaging lines, CNC machines, conveyors, and power distribution panels. The DFJ-500 protects drives, MCCs, and feeder circuits while minimizing nuisance trips thanks to its high-speed response. Its Class J design and clip-lock connection also suit retrofit projects and panel upgrades where reliability and install speed matter.
The DFJ-500 carries UL Listed and CSA Certified safety validation, plus CE marking and RoHS compliance for global markets. These certifications support regulatory compliance, enable cross-border procurement, and simplify QA programs across multinational facilities. The non-indicating design also simplifies spare-parts management while maintaining rigorous protection standards.
DFJ-500 contributes to lower lifecycle costs by delivering dependable protection that reduces downtime and maintenance needs. The non-indicating design minimizes diagnostic complexity, while the clip-lock interface shortens field service time and replacement cycles. For ROI, expect reduced MTTR, fewer nuisance trips, and easier stocking of compatible Bussmann series parts in global facilities.
