FAQs
The DFJ-125 uses blade-end x blade-end connections and a 6 inch length, designed for standard fuse holders and Class J panels. Ensure compatibility with Melamine-tube fuses and verify clearance for 600 Vac applications. Confirm the holder’s physical fit and electrical clearance to avoid contact or arcing.
The fuse is rated for 125 A with an interrupt rating of 200 kAIC at 600 Vac and up to 450 Vdc. It is designed for 600 Vac or less and supports Class J protection, offering fast fault interruption for high‑speed protection needs in electrical protection and circuit control.
Yes. Its high-speed interruption (200 kAIC) at 600 Vac and blade-end Class J design make it ideal for motor drive panels and servo systems where rapid fault clearance minimizes downtime and prevents damage to drives and power supplies.
The DFJ-125 is UL Listed, CSA Certified, and CE RoHS compliant. These certifications support safety compliance, regulatory acceptance, and environmental responsibility across global installations.
The fuse aligns with standard Bussmann series parts, enabling easier procurement and consolidation of spares. Its durable Class J, non-indicating design and 6 inch form factor simplify replacements, reducing downtime, avoiding mismatched protections, and lowering lifecycle costs in automation environments.
