Fuses and fuse holders

Bussmann series Class J fuse blocks and holders

Eaton’s Bussmann® series power distribution fuse blocks (PDFB) combine a fuse block and power distribution block into one component. This patented design simplifies your panel layout and uses up to 65% less panel space. Additionally, it lowers inventory costs while reducing installation time and labor by 33%. Bussmann series PDFBs are available for Class J ferrule and knifeblade fuses. PDFBs up to 60 amps feature DIN-Rail and panel mount versatility for ease of installation. Additionally, PDFBs use fewer wire connections, reducing watts loss and overall operating temperature of the panel.
