Fuse Holder for Class R Fuses
The Littelfuse LFR60030-3CID is a three-pole fuse block rated for 30 A at 600 V AC/DC. It accepts Class R fuses up to 5 in length and 13/16 in diameter, including series such as A6D-R, FRS-R, and TRS-R. The transparent thermoplastic body features indicating, rejection-style clips that are spring reinforced. It is designed for bolt-down or DIN rail mounting in electrical panels.
Box Lug Terminals for 14 to 6 AWG
This holder replaces older blocks that lack indicating clips or rejection features, helping prevent incorrect fuse insertion. The jump is worth it when a design requires visual confirmation of a blown fuse and positive rejection of non-Class R types. Box lug connectors accept solid or stranded wire from 14 to 6 AWG, simplifying field wiring without special tools.
600 V Rating and Physical Envelope
The 600 V rating limits use to circuits at or below that voltage, and the three-pole width fixes the panel footprint at 4.25 in wide by 6.56 in long. Height is 2.07 in, so vertical clearance must accommodate that profile. Buyers needing more poles, higher amperage, or a different mounting style cannot use this model.

Questions about this item
What mounting space does the 4.25 in wide by 6.56 in long fuse block need?
The block measures 4.25 in wide, 6.56 in long and 2.07 in high; it mounts by bolt-down or DIN rail, so allow clearance for both the footprint and the rail clip.
How do I install the box-lug terminals on 14 to 6 AWG wire, and what step is often missed?
Strip the wire to the lug depth, insert fully into each box lug, then torque the screws; the step often missed is verifying the spring-reinforced clip seats the Class R fuse before energising.
When should the transparent indicating window be inspected or the block replaced?
Inspect the window after any fault trip; a dark or melted window means the fuse operated and the block should be replaced, otherwise the thermoplastic body and clips need no scheduled maintenance.
