V11.1 : 27143105
Feature: High current rating and multi-port design (1250A, 4P) → Business Impact: Supports heavy-duty busbar currents with a single, reliable copper termination, reducing the need for parallel connections and potential contact resistance variability. Application: Ideal for switchgear and CT interfaces in industrial power distribution. Feature: XT7/E1.2W copper connections → Business Impact: Delivers low contact resistance and superior thermal performance, lowering maintenance frequency and improving system uptime. Application: CT terminations in high-current assemblies. Feature: Compliance and standards alignment (ETIM EC000635, eClass 27143105, REACH, WEEE) → Business Impact: Eases procurement workflows and regulatory auditing, enabling fast supplier qualification and risk reduction. Application: Global supply chains and panel builders seeking standardized parts. Feature: Mounting and installation guidance (System pro E power RBBS CH – mounting instruction for CTs) → Business Impact: Speeds field installation, reduces on-site torque variances, and improves repeatable quality. Application: On-site CT mounting and busbar assembly. Feature: Packaging and logistics data (WEEE packaging disposal, net/gross weight) → Business Impact: Improves logistics planning, reduces freight surprises, and supports environmental compliance. Application: Site deliveries and warehouse stocking for large equipment projects. In practice, engineers benefit from compatibility with System pro E power ecosystems, clearer spares management, and predictable project timelines, while procurement gains from standardized classifications and clear packaging guidance. The result is safer, more efficient power distribution installations with lower total cost of ownership.

FAQs
The 1STQ007443B0000 copper connections are designed for CT terminations and CT mounting within System pro E power environments. With a 1250A rating and 4P configuration, it accommodates high-current busbar layouts and 4-pole CT interfaces, simplifying integration with ABB’s System pro E power ecosystem and reducing custom mounting work on site.
Key specifications include XT7/E1.2W copper connections, 1250A current capacity, 4 poles, and D600 compatibility. Installation considerations focus on correct CT alignment, torque limits per the mounting instruction, and adherence to System pro E power guidelines to ensure reliable contact pressure, thermal performance, and long-term durability.
The product aligns with ETIM 8/9 EC000635 and eClass V11.1 27143105 classifications, along with REACH information and WEEE categories. These classifications streamline supplier selection, enable consistent data handling in procurement systems, and support regulatory compliance across global supply chains.
Package Level 1 Units: one piece per package, with a net weight of 28.9 kg and gross weight of 30.056 kg per package. WEEE packaging disposal guidance applies, aiding environmentally responsible handling. Delivery planning should account for the large equipment nature and appropriate lifting/rigging considerations on site.
The 1250A 4P XT7/E1.2W copper connection delivers low contact resistance and superior thermal performance, reducing degradation risks under overload. This translates to lower maintenance frequency, diminished downtime, and a lower total cost of ownership over the equipment lifecycle, particularly for high‑duty switchgear and CT interfaces.
