The ABB S203-C25 is a 3-pole miniature circuit breaker rated 25 A with a Trip Curve C characteristic, designed for DIN-rail mounting in distribution panels and control cabinets. The 10 kA interrupting rating at 277 VAC means it can safely clear a bolted fault up to 10,000 A without welding contacts or cascading failure upstream — sufficient for most commercial and light industrial panelboards where the prospective short-circuit current stays under that threshold.
