FAQs
DFJ-5 uses ferrule-end terminations, simplifying secure connections in standard terminal blocks. Ensure terminal ferrules match the fuse size and ampacity, and mount within the specified two-inch body length to maintain proper clearance and heat dissipation. This compatibility supports quick retrofits in existing control panels without specialized tools.
DFJ-5 is UL Listed and CSA Certified, confirming adherence to safety and performance standards. It is CE Marked and RoHS compliant, ensuring environmental and regulatory alignment across global markets. These certifications facilitate multi-region sourcing and reduce compliance-related procurement risk.
The DFJ-5 is rated for 5 A and 150 Vac/dc, with Class J construction. This combination provides fast fault clearing for small to mid-range control circuits while ensuring compatibility with typical drive and panel power supplies. It balances protection with selectivity to minimize unnecessary outages.
Best suited for industrial control panels, machine drive circuits, and feeder lines in automation systems. Its compact size and ferrule-end design ease retrofits in dense control cabinets, and its fast-acting characteristics protect power electronics, sensors, and wiring harnesses from short-circuit damage.
Expect reduced downtime from quicker fault clearance and more reliable protection for drives and controls. The UL CSA CE certifications simplify vendor qualification, while the compact form factor lowers install time and returns value through longer component life and fewer nuisance trips in busy production environments.
