Drive Fuse Class J

DFJ — 600Vac/450Vdc, 1-600A High Speed Fuse

Description: High speed, current-limiting fuse. The Bussmann

Drive Fuse will provide maximum protection for AC and DC

any branch circuit fuse to protect power semiconductor

devices that utilize diodes, GTOs, SCRs and SSRs.

Construction: Melamine tube with silver fuse element.

Ratings:

Volts — 600Vac (or less), 450Vdc (or less, 30-600A)

Amps — 1-600A

IR — 200kA RMS Sym., 100kA DC

Agency Information:

CE, Std. 248-8, Class J, UL Listed, Guide JDDZ, File E4273,

CSA Certified, Class 1422-02, File 53787.
