ABB 1SDA116343R1 Moulded Case Circuit Breaker - IEC Standard

The 4-pole P2N 250 TMD 125-1250 MCCB provides precise current protection with a setting range of 87.5–125 A, enabling tight coordination and reduced nuisance trips in busy control panels. This translates to measurable uptime gains and lower maintenance costs in high-availability facilities. Front terminal connections simplify wiring during installation and retrofit, accelerating commissioning while ensuring robust safety margins in 500 V AC / 250 V DC environments. The unit’s 125 A rated current and 6.60 W power loss support energy efficiency goals and operation within typical industrial cycles, improving overall system reliability. Compliance with IEC standards, RoHS, and CMRT/TSCA declarations reduces regulatory risk and simplifies procurement across global supply chains, boosting supplier sustainability metrics. With 140 mm width, 150 mm height, and 70 mm depth, the compact footprint supports higher panel density and easier service access. The 4P configuration also enables safe disconnection of multiple conductors, reducing fault propagation in complex switchgear. Industry professionals will value the predictable thermal performance and durable mechanical design for long service life in factory automation environments.
