It mounts on DIN rail and is rated for 277 VAC and 125 VDC circuits. The C-curve means it trips between 5 and 10 times rated current — that's 125 to 250 A instantaneous — so it's sized for inductive loads like motor starters, contactor coils, and smaller transformers where inrush won't nuisance-trip a B-curve but you don't need the D-curve's wider window. Interrupting rating is 6 kA at 277 VAC and 10 kA at 125 VDC, which covers standard panel fault levels in commercial and light industrial distribution.","metaTitle":"ABB S203M-C25 MCB 3-Pole 25A C-Curve DIN Rail","metaDescription":"ABB S203M-C25 miniature circuit breaker, 3-pole, 25 A, C-curve, 277 VAC / 125 VDC, 6 kA interrupting rating.
