The ABB S202M-C10 is a 2-pole miniature circuit breaker from the S200M series, rated at 10 A with a Trip Curve C characteristic.
The 10 A rating and Trip Curve C mean this breaker is sized for general-purpose loads with moderate inrush — lighting banks, small motor circuits, control transformers — where the magnetic trip point at 5–10× rated current clears short circuits without nuisance tripping on startup. The 6 kA interrupting rating at 277 VAC covers most commercial and light industrial panel fault levels; the 10 kA DC rating at 125 VDC suits DC auxiliary circuits in UPS or solar combiner boxes.
