FAQs
Its design suits industrial motor drives, conveyors, pumps, and general control circuits. With a 225 A rating and 600 Vac maximum, the DFJ-225 protects downstream equipment during start-up and inrush, reducing nuisance trips and unplanned downtime. The non-indicating Class J fuse keeps panel clutter to a minimum, while the melamine tube provides robust thermal performance in harsh environments.
Key specs include 225 A amperage rating, 600 Vac or less voltage rating, 450 Vdc or less, and interrupt ratings of 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc. It is a Class J, non-indicating fuse with a melamine tube, designed for fast interruption and dependable operation in demanding automation environments.
Yes. The DFJ-225 follows the Bussmann DFJ family design, offering consistent sizing, mounting, and electrical characteristics with other DFJ devices. This compatibility simplifies spares stocking and reduces engineering adjustments when replacing a failed fuse in drives or panels. Standard packaging and mounting footprint help streamline panel design and service operations.
DFJ-225 is UL Listed and CSA Certified, CE Marked, and RoHS compliant, ensuring safety, electrical performance, and regulatory compliance across global installations. These certifications support procurement, reduce risk for audits, and enable faster project approval in industries like automotive, packaging, and process automation. They also reassure end users about reliability and traceability.
Because the DFJ-225 is a non-indicating Class J fuse, maintenance intervals focus on panel inspection and correct replacement rather than status indicators. Its fast-acting protection reduces fault-related downtime, lowering total cost of ownership. With UL and CSA certifications, procurement is straightforward, minimizing spare part lead times and improving uptime in high-demand manufacturing lines.
