The A9F03632 is a Schneider Electric Acti9 iC60N miniature circuit breaker — 1P+N, 32 A rated current, curve B, with a 36 kA breaking capacity at 12–60 V AC.
Snaps onto DIN rail (mounting support: DIN rail). Occupies 4 x 9 mm pitches — 36 mm wide, 91 mm tall, 78.5 mm deep. Double terminals top and bottom accept 1–35 mm² rigid or 1–25 mm² flexible; strip length 14 mm, torque to 3.5 N·m. IP20 finger-safe front, but the terminals are live when the breaker is on — standard panel practice. Neutral on the left, toggle control, trip indicator visible through the front. Pollution degree 3, overvoltage category IV, so it's rated for the incoming side of a distribution board, not just downstream sub-circuits.
