Bussmannn TCF70RN - Time-Delay Fuse 70A@600V (300kA AIC)

Bussmannn TCF70RN is a time-delay low-voltage fuse designed for circuit protection in industrial power distribution systems. Rated for 600V AC/DC applications with a 70A current capacity, it features a single-barrel CF-class construction capable of interrupting 300kA short-circuit currents. The fuse's time-delay (TD) characteristic provides overload protection while withstanding temporary inrush currents, manufactured to US standards in a compact 1 lb package. Typical applications include motor branch circuits, transformers, and feeder protection in commercial/industrial facilities.
