FAQs
DFJ-100-W is a compact Class J fuse with a melamine tube and non-indicating design. For installation, ensure the fuse block supports Class J devices, observe correct voltage and current ratings (600 Vac max, 100 A), and mount in standard cabling trays or panel rails. Verify clearance and heat dissipation in the enclosure to prevent thermal overload.
Yes. The DFJ-100-W is rated for 600 Vac or less and 450 Vdc or less, with an amperage rating of 100 A. It is suitable for mixed AC/DC control circuits common in motor drives and power distribution within industrial equipment.
The DFJ-100-W is UL Listed, CSA Certified, and CE RoHS Compliant, providing recognized safety, environmental compliance, and global market eligibility for industrial applications.
With fast-acting voltage interruption and high interrupt ratings (200 kAIC at 600 Vac, 100 kAIC at 450 Vdc), the DFJ-100-W minimizes arc energy and equipment damage, reducing repair time and unplanned downtime in critical lines such as conveyors and press lines.
Best used in industrial controls, motor drives, and control panels requiring reliable overcurrent protection, robust regulatory compliance, and a compact footprint suitable for restricted enclosures and retrofit projects.
