Drive Fuse Class J DFJ 600Vac/450Vdc, 1-600A High Speed Fuse Features and Benefits Easily coordinated with existing and new variable speed drives and electric controllers. Standard Class J dimensions allowing the use of readily available fuse blocks, holders, and switches. Allows the lowest let-thru energy of any branch circuit overcurrent protective device. Typical Applications Protection of AC and DC drives Equipment using power semiconductor devices Recommended Fuse Blocks and Holders Fuse Amps 1-Pole 2-Pole 3-Pole Description: High speed, current-limiting fuse. The Bussmann Open Blocks Drive Fuse will provide maximum protection for AC and DC 0-30 J60030-1 J60030-2 J60030-3 drives and controllers and meet NEC branch circuit 35-60 J60060-1 J60060-2 J60060-3 2 protection requirements. The Drive Fuse has the lowest I t of Pyramid Blocks any branch circuit fuse to protect power semiconductor 0-30 JP60030-3 devices that utilize diodes, GTOs, SCRs and SSRs.
