Overview
The ABB Thomas & Betts 54866BEBT is a Color-Keyed® long barrel compression lug engineered for high-integrity copper conductor terminations. Featuring a blank tongue with blind end, this lug is designed for 4/0 AWG conductors across multiple flex wire classifications (G, H, I, K & M) and is rated for systems up to 35kV. The electro-tin plated, high-conductivity copper barrel ensures minimal resistance at the crimp point, making it a reliable choice for industrial, utility, and commercial electrical installations.
Features
- Color-coded barrel (purple) with Die Code 54 for repeatable, mistake-proof crimping
- Long barrel design allows for additional crimps and increased pull-out strength
- Blind end construction keeps the barrel sealed during installation
- Blank tongue — no pre-drilled bolt hole; field-drill to your required bolt size
- Electro-tin plated high-conductivity copper for corrosion resistance and low contact resistance
- UL Listed for terminating copper conductors
- Compatible with 4/0 AWG flex conductors: Class G (37/24), Class H (49 STR), Class I (133 STR), Class K (84 STR), Class M (168 STR)
- Works with ABB T&B crimp tools: TBM15I, TBM15CR-LI, TBM14M, TBM14CR-LI and compatible die sets
