The S801C-C32 is a 1-pole miniature circuit breaker from the ABB S800C series, rated 32 A with a Trip Curve C characteristic. The 15 kA interrupting rating at 230 VAC and 10 kA at 125 VDC tell you it can safely break a short-circuit fault up to those levels without welding the contacts or cascading upstream — that SCCR headroom matters when you're coordinating selectivity in a panel with a higher-rated main breaker.
DIN-rail deployment context
The single-pole width (roughly 17.5 mm per pole) means it occupies one module slot — useful when you're packing multiple breakers into a tight enclosure. Rated for 230 VAC phase-to-neutral or 125 VDC circuits, so it fits typical lighting, control transformer, or DC bus protection applications.
