The ABB S281UX-K10 is a 1-pole miniature circuit breaker from the S280 series, designed for DIN rail mounting in distribution boards and control panels. The K-curve characteristic means it trips between 8 and 12 times rated current, suited for loads with moderate inrush like motor starters and transformers where a standard B-curve would nuisance-trip but a Z-curve is too sensitive.
