Tin plating enhances corrosion resistance for durable, reliable terminations. This directly improves long-term conductivity and reduces maintenance in outdoor, damp, or dirty environments where high-current connections are common. The ABB 1SQA008405R0001 dual lug is designed to terminate four 500 MCM conductors with secure compression and repeatable seating, delivering consistent electrical contact even under thermal cycling and vibration. This combination is critical for switchgear, motor control centers, and harsh industrial enclosures where uptime and reliability are non-negotiable. Dual compression lug design reduces assembly time and minimizes BOM complexity. By consolidating two active terminations into one robust lug, installation becomes faster and less error-prone, especially in tight panel spaces. The tin-plated copper construction provides low contact resistance and durable performance across a broad temperature range, enabling higher current density without sacrificing reliability. Regulatory compliance is straightforward with this ABB accessory. REACH compliance confirms no substances above the 0.1% threshold, and WEEE categorization places the part outside standard disposal scopes, supporting sustainable procurement. The EAN 783175883271 and UNSPSC 39121112 codes simplify stock management and cataloging for procurement teams, helping ensure traceability from vendor to panel. Compatibility and installation advantages matter in fast-paced projects. As an ABB-branded accessory, it integrates seamlessly with ABB enclosures and assemblies, reducing compatibility risk and enabling standardized splices across multiple lines. The lug's form factor and tin plating support easy torque control and reliable crimping with common tooling, cutting commissioning times and improving first-pass insulation and containment. Addressing common objections, this lug delivers a practical balance of current-carrying capability, corrosion resistance, and regulatory alignment, making it a dependable choice for new builds and upgrades in utility, manufacturing, and process industries.

FAQs
To install, prepare the conductor ends by de-oxidizing, align the four 500 MCM conductors with the lug openings, and insert them into the compression lug seat following the tool manufacturer's crimping specification. Use a compatible compression tool for large conductors and inspect seating for full engagement. After crimping, verify continuity and insulation integrity to prevent hotspot or arcing.
Tin plating significantly reduces corrosion risk on copper terminations, maintaining low contact resistance over time. The lug's dual compression design ensures a solid, repeatable grip on four 500 MCM conductors, supporting reliable current transfer even under cycling temperatures and vibration common in industrial environments. This translates to fewer field failures, shorter rework cycles, and a lower total cost of ownership.
Yes. The ABB 1SQA008405R0001 Dual Lug is an ABB-branded accessory designed to complement ABB enclosures and panels, reducing compatibility risk and providing a straightforward path to standardized terminations. It accepts four 500 MCM conductors and leverages tin plating for corrosion resistance, which helps installers maintain consistency across multiple panels. For assurance, verify enclosure specifications against the lug’s 4 x 500 MCM capacity.
This lug carries REACH information indicating no substances above the 0.1 mass percentage threshold and is categorized as WEEE Not in Scope with B2B use. These certifications streamline regulatory compliance across regions and procurement workflows. The accompanying EAN and UNSPSC codes also support traceability and governance in supplier catalogs, enabling compliant sourcing for global manufacturing or utility projects.
The lug’s corrosion resistance and reliable current transfer translate to longer service life, fewer maintenance visits, and faster panel commissioning. The reduction in rework and fewer spare part variations lower total cost of ownership. In projects requiring multiple terminations, standardizing on this lug helps streamline training and inventory management, delivering measurable efficiency gains.
