The 125 A frame size and Curve C trip characteristic (trips between 5× and 10× rated current) make it suited for protecting general-purpose loads like lighting, small motor circuits, and transformer primaries where moderate inrush is expected — not for high-inrush transformer or motor-start duty where a Curve D would be the better call. The 50 kA interrupting capacity at 230 VAC means this breaker can safely clear a fault up to 50,000 A without welding its contacts or rupturing the case — critical for installations with high available fault current, typically downstream of a large transformer or in a main distribution panel. That SCCR headroom simplifies coordination studies and keeps the panel compliant with IEC 60947-2 and UL 489 requirements.","metaTitle":"S802S-C125 ABB High Perf MCB, 2P 125A Curve C, 50kA","metaDescription":"ABB S802S-C125 high-performance MCB, 2-pole, 125 A, Trip Curve C, 50 kA interrupting at 230 VAC.
