Bussmann DFJ-70 - Class J Time-Delay Fuse 70A 600V (200kA AIC Rating)

Bussmann DFJ-70 is a Class J time-delay fuse designed for branch circuit and feeder protection in industrial electrical systems. It features a 600V AC voltage rating and 70A current rating with a 200kA interrupting capacity at 600V for reliable short-circuit protection. The single-barrel construction measures 4-5/8 inches in length and weighs 1 lb, featuring current-limiting characteristics to protect against high fault currents. This fuse complies with UL, CSA, and CE standards including UL 248-8, File E4273, and CSA Class 1422-02, File 53787. Typical applications include motor branch circuits, transformers, and industrial control panels where time-delay characteristics prevent nuisance tripping during motor starting.
