The Schneider Electric A9P52632 is a 1P+N miniature circuit-breaker from the Acti9 iC40 range, rated 32 A with a C-curve trip characteristic. It protects final subcircuits against overload and short-circuit in AC distribution boards, and meets both EN/IEC 60898-1 and EN/IEC 60947-2 — so it's certified for residential as well as industrial isolation duty (suitability for isolation confirmed per 60947-2).
Breaking capacity is 6 kA Icu at 230 V AC per IEC 60947-2, and 4500 A Icn at 230 V AC per IEC 60898-1. The lower Icn (4500 A) is the domestic rating; both are on the same hardware. C-curve means magnetic tripping occurs between 5 and 10 times rated current (5–10 x In), with a tighter tolerance of 8 x In ±20 % per IEC 60947-2. That suits mixed loads with moderate inrush — think lighting, socket outlets, small motor circuits — where you need short-circuit protection without nuisance tripping on startup. Thermal-magnetic trip unit gives you two independent protection elements: a bimetal strip for overload (time-delayed, inverse-time) and a solenoid for short-circuit (instantaneous). No electronics to fail, no auxiliary power needed — it's the workhorse topology for distribution MCBs.
Width is 18 mm (2 x 9 mm pitches), so it occupies one modular unit. Neutral is on the left, which matters when you're laying out busbars or linking to an RCCB. Strip length 14 mm. IP20 on the body, IP40 in a modular enclosure — fine for dry indoor panels; not rated for washdown.
