BUSSMANN Effective August 2016 Technical Data 1048 Supersedes December 2015 SERIES DFJ Class J high speed fuses Agency information UL Listed Standard 248-8, Class J, Guide JDDZ, File E4273 CSA Certified, C22.2 No. 248.8, Class 1422-02, File 53787 RoHS compliant CE Features: Easily coordinated with existing and new variable speed drives and electric controllers. Standard Class J dimensions allow using readily available fuse blocks, holders and switches. Has the lowest let-through energy of any branch circuit overcurrent protective device. Catalog symbol: Typical applications DFJ- Protection of AC and DC drives Equipment using power semiconductor Description: devices The Bussmann series DFJ drive fuse is a Catalog numbers (amps): high speed, current-limiting fuse that provides DFJ-1 DFJ-15 DFJ-60 DFJ-200 maximum protection for AC and DC drives DFJ-2 DFJ-17.5 DFJ-70 DFJ-225 and controllers and meet NEC branch circuit protection requirements. The drive fuse has the DFJ-3 DFJ-20 DFJ-80 DFJ-250 2 lowest I t of any branch circuit fuse to protect DFJ-4 DFJ-25 DFJ-90 DFJ-300 power semiconductor devices that utilize DFJ-5 DFJ-30 DFJ-100 DFJ-350 diodes, GTOs, SCRs and SSRs.
