The ABB 1SDA068059R1 is a three‑pole molded case circuit breaker (MCCB) from ABB’s Tmax XT3N series designed for industrial and commercial low‑voltage power distribution protection. It features a thermo‑magnetic (TMD) trip unit with adjustable protection settings, providing reliable overload and short‑circuit protection across a broad current range. The breaker is built for fixed installation with front bolt terminals and is suitable for AC and DC applications typical of main, feeder, and motor circuit protection. With robust interrupting capabilities and compliance with IEC standards, this MCCB ensures safe interruption of fault currents in demanding electrical systems.
