The ABB S201P-D32 is a DIN-rail miniature circuit breaker from the S200 family, carrying a D32 trip curve. That D curve means it's designed for loads with high inrush — motor starters, small transformers, or lighting banks — where the magnetic trip threshold sits higher than a B or C curve, avoiding nuisance trips on startup. It snaps onto standard 35 mm DIN rail and occupies a single module width, so it fits right into an existing panelboard or distribution board without re-spacing.
Mounts directly on 35 mm DIN rail — no adapter needed. The D32 curve is printed on the face; verify nameplate matches your PO before racking. Spring-cage terminals accept up to 25 mm² conductor, so it handles the incoming feed for a sub-distribution board without pigtails.
