- Extremely current limiting - stops damaging short circuit current faster than any mechanical protective device
- Fast-acting - provides fast-acting protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components
- Reliable interruption of all over currents upto 200000 A
- Longer equipment life - current limiting design reduces damage to equipment caused by heating and magnetic effects of short circuit currents
- Often permits use of readily available, less costly equipment
- 200 kA at 250 VAC, 20 kA at 125 VDC interrupting rating

Catalog Description: KLNR/KLSR series RK1 fast-acting fuses were the earliest type of current-limiting fuse developed. Their single-element, silver link design enables them to provide fast-acting overload and short-circuit protection. When used to protect inductive loads such as motors, solenoids, and transformers, KLNR/KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLNR/KLSR series fuses may only provide short-circuit protection. We recommend using POWR-PRO™ LLNRK/LLSRK series RK1, dual-element, time-delay fuses in all new applications requiring the current-limiting ability of UL Class RK1 fast-acting fuses, or in existing applications where fast-acting RK1 or RK5 fuses have been opening on harmless system surges such as motor starting currents.
