125 A nominal current aligns with common distribution panels, enabling immediate compatibility with existing switchgear while reducing the need for expensive reconfiguration. The 690 V AC / 500 V DC rated operational voltage and 800 V rated insulation voltage give engineers the flexibility to protect mixed AC/DC loads in modern machine rooms and control panels, enhancing system reliability. Icu up to 100 kA at low voltages and Ics up to 75 kA across typical line voltages provide substantial fault-current protection, minimizing damage during short-circuits and shortening downtime. With 4P construction and a 160 A uninterrupted current rating, operators gain consistent protection for multi-leg feeders and back-up circuits, improving overall safety margins. Durability metrics—8000 electrical cycles and 25000 mechanical cycles—translate into longer service life and lower maintenance intervals in energy-intensive environments. The TM release type and XT1 sub-family support quick installation in plug-in panelboards, reducing commissioning time and potential wiring errors. Compliance features, including CE, RoHS, and CMRT, simplify procurement across global sites while meeting regulatory expectations. The product’s packaging and disposal guidance help facilities manage end-of-life stewardship, contributing to sustainability goals without sacrificing performance. Compatibility with ABB EcoSolutions and standardized terminal connections promotes scalable expansion as plant needs evolve.
