Littelfuse LLSRK090 - Class RK1 Fuse 90A 600V (200kA AIC)

Littelfuse LLSRK090 is a Class RK1 low-voltage fuse designed for overcurrent protection in industrial electrical systems. This 90A current-rated fuse features a 600V AC voltage rating and provides 200kA interrupting capacity at rated voltage for reliable short-circuit protection. The single-barrel construction with 1.31-inch diameter utilizes time-delay characteristics and is designed for clip-style mounting in standard fuse holders. Compliant with industry standards for RK1 fuses, this component is typically employed in motor branch circuits, feeder circuits, and industrial control panels where high-interrupting capacity and time-delay protection are required.
