ABB 1SQA014414R0001 SB INT - 40X 3P CenLwr Protection
Part Number: 1SQA014414R0001
Quick Summary
ABB 1SQA014414R0001 SB INT provides high-current protection for main switchgear in industrial power distribution. Engineers often struggle with limited panel space, wiring complexity, and downtime caused by undersized protection modules. This device aligns with REACH information and WEEE category status, and it also reflects industry expectations for CE marking and robust enclosure protection in electrical protection & circuit control. By pairing a 4000 A, 3P architecture with a compact CenLwr footprint, ABB protection devices deliver reliable performance in space-constrained installations. For buyers, this combination translates to faster installation, reduced wiring errors, and lower lifecycle costs across global deployments, helping ensure uptime and regulatory compliance across critical automated processes.

Feature → Business Impact → Application: The 4000 A rating supports large feeders and motor circuits with fewer protection trips, increasing line reliability and reducing unplanned downtime in manufacturing lines. This translates to higher Overall Equipment Effectiveness (OEE) and predictable maintenance windows for process automation. Feature → Business Impact → Application: CenLwr 40X footprint and 1S/2S mounting save panel space and simplify wiring access, enabling faster panel assemblies and easier retrofits in tight switchgear installations. Application includes compact switchboards and retrofit projects where footprint is a decisive factor. Feature → Business Impact → Application: Material compliance indicators (REACH false, WEEE not in scope) ease regulatory planning across global sites and accelerate supplier qualification for multinational projects. Application includes multinational facilities with strict reporting requirements. Feature → Business Impact → Application: Comprehensive documentation and drawings, including Mechanical Drawings RG_SWBD_40X_9_CenLwr_XS, reduce engineering time and change-order risk during installation and commissioning. Application includes new builds and upgrades in electrical protection & circuit control setups. Feature → Business Impact → Application: Proven ABB build quality and standardization across product families deliver lower total cost of ownership, easier spares management, and improved supplier collaboration for ongoing maintenance of high-current protection schemes.

FAQs
This device uses a cenlwr (center lower) mounting within 40X class switchboards and supports 1S/2S configurations. Ensure your enclosure provides adequate space for the 40X footprint and allows clear access to the incoming and outgoing terminals. Refer to the mechanical drawing RG_SWBD_40X_9_CenLwr_XS for precise dimensions and torque specifications, and verify compatibility with your existing ABB or third-party busbars.
With a 4000 A rating, this unit supports high-load feeders and motor supply circuits without frequent protection trips. The 3P configuration provides balanced protection across phases, improving fault clearance reliability. In practice, customers see improved uptime, simplified protection coordination, and reduced need for external fusing when paired with compatible circuit breakers and cabling rated to this current class.
Yes, in process industries with stringent uptime and fault tolerance. The 40X CenLwr footprint helps fit dense panels; 3P arrangement simplifies wiring; high current rating offers robust feeder protection. Ensure regulatory alignment with REACH and WEEE; check CE marking and IP enclosure protection as required by your facility's design standards.
REACH information indicates no substances above 0.1 mass percentage. WEEE category states product not in WEEE scope. EAN 783175926190 helps with procurement traceability. For other certifications like CE, IP ratings, consult the product datasheet and your regional requirements to confirm alignment with your safety and environmental standards.
The ABB device accelerates commissioning with accessible mechanical drawings and standardized interfaces, reducing maintenance time and field rework. The 4000 A rating minimizes nuisance trips, improving process availability and performance. Long-term supply and support from ABB, combined with clear documentation, translate to lower lifecycle costs and faster return on investment in high-demand applications.
