ABB 1SQA008408R0001 Accessory - Tin Dual Comp Lug, 4 300MCM
Part Number: 1SQA008408R0001
Quick Summary
ABB 1SQA008408R0001 dual comp lug is a tin-plated connector accessory for high-current distribution in electrical enclosures. Engineers often struggle with corrosion-prone lugs that loosen under vibration and heat cycling. This accessory supports REACH compliance and is categorized outside WEEE scope, aligning with B2B procurement needs and long-term cost efficiency. In practice, ABB's tin-lug design delivers secure, vibration-tolerant connections that reduce maintenance and downtime. By simplifying compatibility with ABB and third‑party enclosures, this accessory accelerates panel builds and serviceability. Its capacity for four 300 MCM conductors supports dense power distribution in control cabinets and switchgear, while the tin finish minimizes oxidation across environments.

Tin-plated dual compression lug design significantly improves corrosion resistance and maintains low contact resistance, delivering reliable current paths even in harsh environments. The result is fewer loosening issues from vibration and thermal cycling, reducing maintenance intervals and on-site callouts. This makes it ideal for power distribution in control cabinets, switchgear, and industrial enclosures where dependable connections are critical. The dual compression approach also provides redundancy in contact pressure, which helps sustain performance as conductor sizes and routing evolve over time. With capacity for multiple large conductors, this lug supports up to four 300 MCM conductors, enabling higher wiring density without sacrificing mechanical security. The robust tin finish and copper base resist oxidation, while the compression mechanism maintains consistent torque retention. This is particularly advantageous for feeder applications, motor starters, and distribution blocks in factory automation environments. Compliance features reduce regulatory risk: REACH information confirms no substances above 0.1% by mass, and the WEEE category shows the product is not in scope for consumer waste rules (B2B use). These factors reduce risk during supplier qualification, audits, and cross-border sourcing. In practice, procurement teams gain confidence that the accessory aligns with both global and local environmental requirements. Installation and compatibility are streamlined: as an ABB accessory, it integrates smoothly with existing lugs and enclosure geometries, while also supporting compatibility with third-party enclosures. The tin plating eases solder-free connections and minimizes oxidation during assembly and maintenance windows. The result is faster panel builds, lower labor costs, and improved uptime in automation lines. Industry experience shows that reliable lug connections are a decisive factor in overall system availability. By combining robust current handling, corrosion resistance, and easy installation, this lug helps engineers meet stringent reliability targets while keeping maintenance cycles predictable. For project teams, this means smoother commissioning, fewer field-change orders, and a clear path to compliant, durable power distribution.

FAQs
Yes. The ABB 1SQA008408R0001 is designed as a versatile accessory compatible with ABB and many third-party enclosures. It supports four 300 MCM conductors, enabling secure, plug-and-play installation in typical industrial control cabinets and switchgear. Always verify torque guidance for the specific conductor size and enclosure design to ensure optimal performance.
The lug is built for high-current distribution with a dual compression mechanism that maintains stable contact pressure under vibration and thermal cycling. Its tin-plated copper construction minimizes oxidation, helping sustain low contact resistance and reliable performance in demanding environments such as factory automation and power distribution panels.
Yes. Its capacity for up to four 300 MCM conductors, robust compression, and corrosion resistance make it well-suited for motor control centers, switchgear, and distribution blocks in industrial automation. The design prioritizes reliability in environments with vibration, humidity, and temperature fluctuations, reducing maintenance needs over the life of the installation.
The lug is REACH compliant (no substances above the 0.1% by mass threshold) and is categorized as not in scope for WEEE for B2B use. It carries an EAN of 783175883301 and UNSPSC classification 39121112, supporting regulatory alignment and traceability in industrial supply chains.
Expect reduced maintenance intervals due to improved corrosion resistance and secure clamping, which lowers field service calls and downtime. The tin finish protects against oxidation, enabling longer service life, faster commissioning, and a clearer path to compliant, durable power distribution with fewer change orders during upgrades or expansions.
