ABB S261-C3 DIN Rail MCB, 3A C-Curve Circuit Breaker

The ABB S261-C3 is a DIN-rail mount miniature circuit breaker (MCB) with a 3 A C-curve trip characteristic. It lives in the S260 series — the standard residential and light-commercial line from ABB. The C-curve means it trips between 5 and 10 times rated current, so it handles moderate inrush from small motor loads, lighting ballasts, or transformer primaries without nuisance tripping. That's another SKU that fits the common panel footprint; snaps onto standard 35 mm DIN rail.
