Snaps onto standard DIN rail, so panel integration is straightforward — just clip it in and bus the incoming supply across the three poles. ## Trip Curve B — what it means for selectivity Curve B (3–5× In) means the breaker holds through the short-duration inrush of resistive heaters, lighting banks, and control transformers, but trips fast on a hard short — no nuisance tripping on capacitive loads like a Curve C would handle. For a 80 A feed, that magnetic trip threshold sits between 240 A and 400 A — coordinate downstream with Curve C or D sub-feed breakers to keep the fault closest to the load.","metaTitle":"ABB S803C-B80 MCB S800C 3P B 80A, 15 kA","metaDescription":"ABB S803C-B80 MCB, 80 A, Trip Curve B, 3-pole, 230 V AC, 15 kA interrupting rating.
