ABB 1SDA102706R1 Thermomagnetic Release 3 Pole

ABB 1SDA102706R1 is a three‑pole thermomagnetic release (TMA) designed as an XT5 accessory for ABB SACE Tmax XT5 molded‑case circuit breakers. Listed UL/CSA for 3‑pole XT5 assemblies, it supports a nominal current range of 600 A to 6000 A and is suitable for use in both AC and DC control circuits. The instantaneous trip setting (I3) spans 3,000 A to 6,000 A, enabling rapid protection against high‑level short circuits while providing thermal overload protection via the release’s magnetic and thermal elements. This part is used to tailor protective characteristics in medium‑ to high‑current ABB XT5 MCCB configurations, identified by the manufacturer as TMA 600‑6000 XT5 3p UL/CSA. In practice, technicians select this release to achieve the intended balance of ground‑fault response and overload protection within ABB’s XT5 platform, ensuring compatibility with three‑pole XT5 modules in electrical distribution panels and industrial installs. The 1SDA102706R1 designation corresponds to ABB’s XT5‑series thermomagnetic release configuration for 600–6000 A applications, consolidating reliable overcurrent protection under both AC and DC control schemes.
