D FJ — 600Vac/4 50Vdc, 1- 600A H igh Speed Fuse D escription: H igh speed, current-lim iting fuse. The Bussm ann Drive Fuse w ill provide m axim um protection for A C and DC drives and controllers and m eet N EC ® branch circuit protection requirem ents. The Drive Fuse has the low est I 2 t of any branch circuit fuse to protect pow er sem iconductor devices that utilize diodes, G TO s, SC Rs and SSRs. C onstruction: M elam ine tube w ith silver fuse elem ent. R atings: Volts — 60 0 Vac (or less), 450 Vdc (or less, 30 -60 0 A ) A m ps — 1-60 0 A IR — 2 0 0 kA RM S Sym ., 10 0 kA DC Agency Inform ation: C E, Std. 2 48 -8 , C lass J, U L Listed, G uide JDDZ, File E42 73, C SA C ertified, C lass 142 2 -0 2 , File 5378 7.
