ABB 58163 One-Hole Compression Lug 4/0 AWG 3/8 in Stud Short Barrel

ABB 58163 Compression Lug for 4/0 AWG Copper

The ABB 58163 is a one-hole compression lug designed for terminating 4/0 AWG stranded copper conductors. It features a straight barrel with a standard short length and a 3/8 inch stud hole for secure mounting. The connector is constructed from copper with a tin contact finish and includes an inspection hole for visual verification of wire insertion. It carries CSA certification and UL E9809 listing for electrical safety compliance.

Sustained Load Performance with 35 kV Rating

Under continuous electrical load, the lug maintains a reliable connection up to a maximum voltage of 35 kV. The tin-plated copper barrel resists oxidation and corrosion, preserving conductivity over extended service periods. The compression design creates a permanent, gas-tight joint that resists loosening from vibration or thermal cycling. The yellow color code and die code 62 ensure correct tool selection for a consistent crimp every time.

Single-Hole 3/8 in Stud Fixing Constraint

The defining specification is the single 3/8 inch stud hole, which limits the lug to a single-bolt mounting configuration. Buyers needing a two-hole NEMA pattern or a different stud diameter cannot use this part. The straight tongue angle and 0.15 inch tongue width further restrict compatibility with specific bus bar layouts. Verify the mounting hardware and spacing requirements before selecting this connector.
