KLNR 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, KLNR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLNR series fuses may only provide short circuit protection.
