- 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 600 VAC, 20 kA at 300 VDC interrupting rating

Catalog Description: KLSR series RK1 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, KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, 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 fuses, or in existing applications where fast-acting RK1 or RK5 fuses have been opening on harmless system surges such as motor starting currents.
