ABB 1SDA075135R1 Molded Case Circuit Breaker

ABB SACE Tmax XT3S 225 TMF 150-1500 3P, 1SDA075135R1, is a fixed, three‑pole molded case circuit breaker from ABB’s SACE Tmax XT3S family. It features front-terminal connections for straightforward wiring in panel installations and uses a thermal‑magnetic (TMF) trip unit to provide reliable overload and short‑circuit protection. The 225 A frame size denotes its size class and current‑handling category, making it suitable for protecting distribution circuits and motor feeders in industrial environments. This device is UL/CSA listed, ensuring compliance with common North American electrical safety standards. The XT3S line, including this variant, is rated for operation up to 690 V AC, aligning with typical industrial distribution systems and enabling robust protection in medium‑voltage applications. In practice, this MCCB offers precise, repeatable tripping for protection coordination in panels where space is at a premium, while delivering ABB reliability and consistent performance across the Tmax XT family.
