Fusion 6440F Compression Lug 4/0 AWG

This Fusion 6440F is a one-hole compression lug rated for 4/0 AWG conductors. It suits installers who need a heavy-wall starter or ground connection in automotive or industrial wiring jobs. The straight barrel accepts a 3/8 inch stud for direct bolting to busbars or terminals. Condition is new.

Tin-plated copper barrel with raised pads

The contact material is tin-plated copper formed into a heavy-wall lug with raised pads and a yellow colour code. A crimp tool creates the connection, giving a gas-tight joint that resists vibration and corrosion in daily service. cULus, RoHS, SAE J163 and SAE J1811 listings confirm the build meets recognised safety and material standards.

Replaces worn or undersized starter lugs

Swapping a damaged or smaller lug for this 4/0 AWG unit restores full ampacity at the battery or distribution point. The upgrade is worth it when the existing terminal shows heat discoloration, loose strands or a stud size mismatch. Buyers who need a two-hole pattern or a different stud diameter should select an alternative lug.

Questions about this item

What standard does the cULus listing cover for this 4/0 AWG lug?

The cULus mark confirms compliance with UL and Canadian safety requirements for wire connectors used in power and grounding circuits.

What stud size and hole pattern does the 6440F lug accept?

It has a single 3/8 inch stud hole on a straight heavy-wall barrel with raised pads for secure mounting.

How do you crimp this lug correctly, and what mistake should be avoided?

Use a calibrated 4/0 AWG die, insert the stripped conductor fully, and crimp once; do not re-crimp or rotate the lug, which weakens the joint.
