High-current capability is supported by the 4000 A rating, enabling you to minimize the number of parallel connections in a System pro E Power modular board. This reduces contact resistance, limits heat buildup, and improves overall distribution reliability in critical applications. It is ideal for Main Distribution Boards where heavy feeders require robust, low-impedance links. Flat copper conductors deliver lower resistive losses and better thermal performance, reducing voltage drop and extending component life, which translates to fewer service interruptions and lower maintenance costs in manufacturing environments. Dimensions address space constraints: Product Net Width 120 mm, Net Height 10 mm, Net Depth 364 mm, with a weight of 9.36 kg, allowing seamless integration into existing bus systems without oversized enclosures. Its compact profile supports modular board design and faster commissioning on System pro E Power platforms. Compliance and classification like ETIM EC000635, ETIM EC000635, and eClass 27143105; WEEE B2B ensure procurement alignment with data standards and regulatory requirements, reducing sourcing risk and speeding up approvals in engineered-to-order projects. Packaging of packet 1 piece simplifies stocking, QA, and field installation planning, supporting just-in-time delivery and predictable assembly workflows for OEMs and panel builders.

FAQs
To install the ABB 1STQ007758B0000 N Link - Coupler, follow System pro E Power installation practices for modular boards: position the unit for direct bus connection, align with mating terminals, and secure with the designated fasteners. The unit weighs 9.36 kg and uses flat copper conductors for low impedance paths. Verify continuity and insulation after assembly, and ensure compliance with panel sequencing and torque specifications in the System pro E Power guidelines.
The N Link - Coupler is rated for up to 4000 A and uses flat copper conductors, delivering low resistance and stable current delivery across long bus runs. This combination minimizes voltage drop and thermal stress, improving reliability in continuous operation. It is well-suited for Main Distribution Boards and modular systems where high-current feeders are required and where reduced parallel connections simplify thermal management.
Yes. The N Link - Coupler is designed for Main Distribution Boards within industrial automation, supporting System pro E Power modular boards and providing robust bus connections for high-current feeders. Its compact footprint and 364 mm depth help optimize space in dense panel layouts, enabling scalable expansion without major rework and sustaining reliable power distribution in demanding environments.
This product aligns with ETIM 8/EC000635 and ETIM 9/EC000635, as well as eClass V11.1 with code 27143105, ensuring consistent data for procurement and cross-compatibility. WEEE B2B and WEEE Category 5 support responsible disposal and business-to-business use. These standards reduce sourcing risk, speed up ordering, and improve data quality in ERP and procurement workflows, which is critical for large-scale projects.
Using the 4000 A N Link coupler reduces heat and contact resistance, lowering the risk of connection failures and downtime. Fewer field replacements and shorter commissioning times translate into lower maintenance costs and a faster return on investment. The 1 piece per packet packaging also simplifies inventory planning and accelerates project timelines for OEMs and panel builders.
