Littelfuse UL Class Fuse RK5 Class Time-Delay 80A 250V AC Non-Indicating

The Littelfuse Class RK5 80A Time‑Delay Fuse provides reliable overload and short‑circuit protection for industrial and commercial electrical systems. Its time‑delay, dual‑element design allows temporary inrush currents—ideal for motors, transformers, and inductive loads—while still delivering fast response to sustained faults.

This is a non‑indicating fuse, offering a cost‑effective solution for panels and equipment where blown‑fuse indication is not required.
