ABB 1SDA104959R1 Accessory for Tmax XT - 380...440 VAC

Feature → Business Impact → Application: The 1SDA104959R1 is designed as a loose or configurable undervoltage release accessory for Tmax XT XT5-XT6, enabling precise control of circuit-breaker tripping logic. This translates to improved safety margins and reduced risk of unexpected outages in critical motor-control panels. In real-world terms, the component supports consistent undervoltage operation across 380–440 V AC systems, helping maintenance teams avoid costly downtime and facilitating faster fault isolation. Feature → Compatibility → Application: It is specifically suitable for XT5 and XT6 models, ensuring effortless integration with existing Tmax XT configurations and minimizing retrofit effort in legacy installations. This compatibility is especially valuable in high-availability plants that require plug-in readiness and minimal wiring changes. Feature → Compliance → Application: The product carries RoHS and REACH declarations plus IEC 60947-2 and UL 489 standards, which streamlines procurement for regulated environments and accelerates approvals in safety-critical applications. This reduces compliance overhead in panel-building projects. Feature → Environmental & Packaging → Application: Packaging disposal information and compact product net weight (0.123 kg) support efficient logistics and recycling programs, lowering total cost of ownership. Feature → Operational Insights → Application: With clear order codes (KXTFYUC6 for US/Canada) and a defined minimum order quantity (1 piece), stocking and supply-chain planning become predictable, supporting just-in-time procurement for manufacturing lines. These attributes collectively enable measurable efficiency gains, improved regulatory compliance, and cost reductions in engineered systems that rely on Tmax XT protection strategies.
