Product Main Type
ReliaGear UL891
High current rating of 4000 A enables dense power distribution in large control panels and switchgear. This capability reduces the number of separate assemblies, shrinking footprint and simplifying cabling while maintaining safe protection margins. It is especially beneficial for heavy automation lines, machine centers, and critical manufacturing cells where peak-load reliability directly affects line throughput and uptime. ReliaGear UL891 architecture provides a standardized protection module approach, signaling predictable performance and simpler maintenance. By aligning with a recognized panelboard standard, it supports consistent parts availability, faster commissioning, and easier retrofits for aging protection schemes. This translates to lower total cost of ownership and smoother procurement for system integrators working on large ABB and third-party switchgear projects. REACH Information and WEEE compliance statements underpin environmental and regulatory readiness. The product does not contain substances above 0.1 mass percent, and it falls outside WEEE scope, reducing regulatory overhead in global deployments. For multinational installations, this compliance posture minimizes audit findings and supports sustainable asset management while aligning with corporate ESG goals. Installation compatibility with ABB protection and circuit-control ecosystems enables faster retrofits and cohesive wiring schemes. The solution integrates with existing ReliaGear and ABB protection assets, supporting modular upgrades without major rerouting. For panel shops and on-site builds, this compatibility shortens training time for technicians and reduces commissioning risk by preserving familiar terminations and layout conventions. Beyond initial setup, the protection strategy offers measurable reliability gains and lifecycle value. High-current capacity supports future expansion without switching hardware, while the consolidated protection approach minimizes maintenance intervals and unplanned downtime. Operators benefit from clearer diagnostics, quicker fault isolation, and a stronger baseline for predictive maintenance programs in demanding industrial environments.

FAQs
Installation planning should start with confirming UL891 panel compatibility and ensuring the 4000 A rating aligns with the panel's busbar and terminations. Use standard ReliaGear mounting patterns, verify bus connections match the 1SQA014951R0001 accessory set, and follow ABB wiring practices to minimize commissioning time and avoid mis-termination. This approach reduces risk during retrofit projects and maintains system interoperability.
Key specs include a 4000 A current rating and ReliaGear UL891 architecture, which provides standardized protection modules for reliable operation. The device also adheres to REACH information guidelines (no substances above 0.1 mass%), and is categorized as WEEE not in scope. These factors collectively support high-load distribution with regulatory confidence across global deployments.
Yes. The 4000 A rating enables robust distribution for demanding manufacturing environments, supporting heavy automation lines and machine centers. Its ReliaGear UL891 basis ensures compatible panelboard integration, while REACH and WEEE compliance support safe, regulator-ready installations across international sites. This makes it a practical choice for scalable, high-demand automation architectures.
The product aligns with RELIA Gear UL891 standards (UL891-based design), along with REACH compliance and WEEE scope considerations. REACH confirms no harmful substances above threshold levels, and WEEE in-scope status is avoided, simplifying global deployment and audits. These certifications reduce regulatory complexity while supporting sustainable, compliant asset management.
ROI benefits stem from higher protection reliability and reduced downtime due to robust 4000 A performance and standardized UL891 architecture. Maintenance is streamlined by consistent parts availability and familiar ReliaGear interfaces, reducing spare-part variety and training time. Over the asset lifecycle, this translates to lower operating costs and more predictable maintenance planning.
