FLSR080 is Littelfuse’s 80A configuration in the FLSR Series, built as a Dual-Element Time-Delay Class RK5 Fuse for 600V AC / 300V DC service. Installation uses cartridge / clip hardware and ferrule / blade (amp-dependent) contacts; the principal interrupting rating is 200kA AC. Published dimensions for this rating/configuration are 200.0mm length; 32.6mm max body diameter. Its dual-element time-delay behavior is intended to ride through normal motor inrush while protecting against overloads and short circuits. Typical uses cover Motor, Transformer, Service Entrance, Feeder Circuits, general-purpose circuits. Check UL 248-12 and the manufacturer datasheet before final selection.
