The ABB S282UC-K25 is a 2-pole miniature circuit breaker from the S280UC series, rated 25 A with Trip Curve K. It mounts on a standard DIN rail — typical for panel integration in industrial control cabinets or distribution boards.
Curve K means the magnetic trip threshold is set to 8–12× rated current — designed for loads with moderate inrush, such as motor circuits or transformer primaries, where a standard B or C curve would nuisance-trip on startup. The 25 A rating handles continuous loads up to that level; the 2-pole configuration breaks both line and neutral (or both phases) simultaneously.
