ABB 1SDA053681R1 Shunt Opening Release - UL/CSA

Voltage compatibility unlocks installation flexibility. The release supports 110–127 VAC and 110–125 VDC with an AC/DC current type, enabling a single accessory to cover regional variants and reduce stocking complexity. By aligning Tmax T tripping logic with precise actuation, the device minimizes wiring errors during installation and commissioning and accelerates panel builds. In field trials, teams report fewer configuration mismatches and faster fault isolation, translating into smoother turnarounds and improved first-pass yields on critical safety circuits. Configuration and mounting simplicity drive efficiency. The option is loose or configurable, allowing adaptation to different panel depths, conduits, and cable runs without reworking protection logic. It is designed for the Tmax T family and is suitable for T1, T2, and T3 units, ensuring dependable actuation across the range. As an ACC product in the Tmax T ecosystem, it integrates with SACE Tmax T protection schemes while preserving straightforward procurement for OEMs. Standards and certifications underpin safe global deployment. IEC-based design, UL/CSA listings, and CE declaration of conformity support cross-border projects and simplify regulatory qualification. These credentials help maintain protective coordination and provide traceability for safety-critical installations. When paired with compatible Tmax T assemblies, the release maintains consistent performance across environments, reducing risk and ensuring that safety requirements are met in industrial automation facilities. Practical specifications aid logistics and maintenance. The net weight is about 1 kg, with EAN 8015644546922 for straightforward stocking. Minimum order quantity is 1 piece, enabling pilots or single-location deployments. Customs tariff 85389099 aligns with standard classifications for switch spools and power circuit accessories, simplifying import processes. This packaging and data support rapid procurement, predictable lead times, and scalable deployment across multiple lines. Industry insight suggests measurable gains in commissioning speed, protection coordination, and uptime when using a compatible Tmax T shunt release, especially in OEM and high-volume manufacturing environments.
