Littelfuse IDSR30 - RK5 Time-Delay Fuse 30A@600V (200kA AIC)

Littelfuse IDSR30 is a time-delay low-voltage fuse designed for circuit protection in industrial power distribution systems. This RK5-class fuse features a 600V AC/DC rating with a 30A current capacity and 200kA interrupting capacity at rated voltage, housed in a compact 1.06-inch diameter ferrule-rejection barrel construction. The TD (Time Delay) characteristic provides motor start-up and transient current tolerance while maintaining reliable overload protection, complying with industry standards for power circuit applications. Typical uses include protecting transformers, motor circuits, and feeder lines in commercial and industrial electrical panels.
