DFJ-20 Datasheet, PDF (1/4 Pages) Cooper Bussmann, Inc. – DFJ - 600Vac/450Vdc, 1-600A High Speed Fuse

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
drives and controllers and meet NEC^® branch circuit
protection requirements. The Drive Fuse has the lowest I²t of
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.
