400 kcmil 5/8" 1-Hole Flared Barrel Copper Lug, Blue | Techspan® BLU040SFL

This short flared barrel copper lug is designed for 400 kcmil conductor terminations where a one-hole tongue, 5/8" stud hole, and compact barrel length are required. The lug is manufactured from high-conductivity seamless copper tubing and tin-plated to help inhibit corrosion.

The flared barrel entry supports easier cable insertion, especially with fine-stranded flexible cables, and helps reduce strain during cable flexing and movement. An inspection window allows visual confirmation of full cable insertion before crimping, supporting accurate installation.

Key technical attributes:

• 400 kcmil conductor size
• 313 MCM diesel locomotive cable range
• Standard flared barrel design
• Blue color-coded barrel with die index marking
• One-hole tongue with 5/8" stud hole
• 35 KV voltage rating
• UL Listed and CSA Certified construction
• Compatibility with Class B, C, I, K, H, G, M, and DLO conductors

The lug is listed for use with compatible tooling styles including Penn-Union, Burndy, T&B, Huskie, Greenlee, and Versa-Crimp. Its marked barrel, die index reference, inspection window, and defined strip length provide clear installation guidance for electrical connection work requiring a copper compression lug with controlled conductor insertion and crimping compatibility.
