Littelfuse FLNR-150 - Class RK5 Fuse 150A 600V AC (200kA Interrupting Rating)

Littelfuse FLNR-150 is a low-voltage current-limiting fuse designed for branch circuit and feeder protection in industrial electrical systems. It features a 150A current rating and a 600V AC voltage rating, providing reliable short-circuit protection. The fuse body is constructed with a durable ceramic material and features a visible rejection-style indicator for safe visual status confirmation. This fuse is UL listed and CSA certified, meeting Class R rejection requirements to prevent installation in non-current-limiting fuse holders. Typical applications include motor control centers, industrial control panels, and power distribution equipment where high interrupting capacity is required.
