FAQs
The DFJ-90 uses a clip-lock connection designed to fit standard Class J fuse holders, enabling quick, secure installation in common control panels and enclosures without custom adapters. This reduces commissioning time and minimizes wiring errors during replacement.
The DFJ-90 is rated for 90 A with voltage up to 600 Vac (or 450 Vdc), and provides 200 kAIC interrupt capability at 600 Vac and 100 kAIC at 450 Vdc. These ratings support fast fault interruption in motor drives and other high inrush applications, protecting both equipment and personnel.
Yes. With its Class J construction, quick-install clip-lock design, and high interrupt rating, the DFJ-90 is well-suited for motor control centers, packaging lines, CNC machines, and other automation equipment requiring reliable overcurrent protection.
DFJ-90 carries UL Listed and CSA Certified marks and CE RoHS compliance, ensuring conformity to North American and European safety and environmental standards for industrial equipment.
Because the DFJ-90 is non-indicating, visual fault status requires panel indicators or monitoring. Replace with the same model and ratings, inspect wiring for heat and arcing damage, and verify secure clip-lock seating to maintain protection integrity.
