Eaton Specification Sheet - DFJ-80-W
The DFJ-80-W provides a 200 kAIC interrupt rating at 600 Vac. This rapid fault clearance reduces arc exposure and protects downstream equipment in panels and motor control centers. The device also supports a voltage rating of 600 Vac or less and 450 Vdc or less, enabling protection across both AC and DC circuits with a single, standard component in mixed-control environments. Class J, clip-lock construction with a melamine tube ensures compatibility with standard Bussmann fixtures, enabling quick field replacements and consistent panel performance in industrial control panels and machine wiring. The non-indicating design keeps panel interiors clean while maintaining reliable operation and simple visual inspection. Certifications and RoHS compliance (UL Listed, CSA Certified, CE Marked) streamline procurement and regulatory reporting, reducing compliance overhead. With a compact footprint (4.83 in L Ă— 1.19 in H Ă— 1.18 in W) and a weight of 0.31 lb, it fits standard enclosures and supports straightforward retrofits and maintenance planning.
