FAQs
The 1SDA104949R1 is designed as a YU-C undervoltage release accessory for Tmax XT5 withdrawable circuit-breakers. It is part of the Tmax XT ecosystem and is best paired with XT5 units. For XT6 compatibility, verify frame type and consult the product manual, but the XT5 configuration ensures optimal performance in XT5 applications. The US/Canada order code KXT5YUCW2 supports procurement within the relevant markets.
The accessory operates at 48 to 60 V in both AC and DC forms (AC/DC current type). It adheres to key standards IEC60947-2 and UL489, ensuring safety and interoperability in low-voltage MCC and control panels. It also complies with RoHS and REACH declarations, supporting regulatory requirements across global regions.
Installation is designed to be loose or configurable, allowing flexible mounting within Tmax XT5 withdrawable frames. It plugs into the undervoltage release position and wires according to the XT5 auxiliary wiring diagrams. This approach minimizes retrofit complexity and reduces commissioning time while preserving module accessibility for maintenance.
Key certifications include IEC60947-2 and UL489 for low-voltage molded case breakers. The accessory also carries RoHS information and RoHS status (EU 2011/65/EU and 2015/863 amendments), REACH declaration, CMRT, and TSCA declarations. These certifications facilitate global compliance, supplier qualification, and safer supply chain management.
Using the ABB 1SDA104949R1 reduces unplanned downtime by ensuring reliable undervoltage protection and safer startups. Its standardized part within the Tmax XT family simplifies procurement (MOQ 1 piece, EAN 8015644070410) and maintenance, leading to lower spare parts inventory and faster repair cycles in high-volume manufacturing environments.
