ABB OXB250E3X2QB 1SCA153459R1001 Automatic Transfer Switch 3P 250 A

ABB OXB250E3X2QB (article 1SCA153459R1001) is an open-style automatic transfer switch from ABB's TruONE family, built to monitor two power sources and transfer the load to the available supply when the primary source fails. This unit uses delayed transition I-O-II operation with an integrated Level 2 DIP controller, and accepts supply voltages from 200 to 480 VAC with ±20% tolerance.

Technical specifications:

• Series: OXB250E3X2QB (TruONE family)
• ABB article number: 1SCA153459R1001
• EAN: 6417019844855
• Type: Open style automatic transfer switch (ATS)
• Transition type: Delayed transition, I-O-II operation
• Controller: Level 2, DIP configuration
• Voltage range: 200 to 480 VAC (±20% tolerance)
• Design: Switch and controller integrated in one self-contained unit

Features and benefits:

• Switch and controller housed in a single self-contained unit, cutting the number of wires and field connections and speeding up installation
• Wide voltage acceptance (200 to 480 VAC with ±20% tolerance) covers a broad range of distribution systems without stocking separate variants
• Modular internal components and predictive maintenance capability reduce unplanned downtime and keep service costs low
• Advanced connectivity architecture supports integration with monitoring and building management systems
• Performance validated beyond standard test requirements, providing confidence in critical power continuity applications

Applications:

• Emergency generator transfer switching in commercial, industrial, and institutional facilities
• Critical power backup for data centres, hospitals, and essential infrastructure
• Standby power systems where a neutral (off) position between sources is required during transition
• Industrial installations spanning a wide range of distribution voltages
