Benefits
UL Class J high speed; full range current-limiting fuses provide maximum protection for AC and DC drives and controllers. The UL Class J Bussmann series DFJ fuse has the lowest I2t of any branch circuit fuse to protect power semiconductor devices that utilize diodes; GTOs; SCRs and SSRs. The DFJ fuse combines the performance of high speed fuses in a full range Class J branch circuit package; allowing the use of readily available Class J fuse blocks; holders and switches. The DFJ uses standard Class J holders and blocks. See section 8 for available catalog numbers.
