The Schneider Electric A9F04732 is an Acti9 iC60N miniature circuit breaker rated 32 A with a C-curve trip characteristic, 3P+N poles, and a thermal-magnetic trip unit.
The breaking capacity varies by voltage: 36 kA Icu at 12…133 V AC, 20 kA Icu at 220…240 V AC, 10 kA Icu at 380…415 V AC, and 6 kA Icu at 440 V AC per EN/IEC 60947-2. Under the 60898-1 standard it carries 6000 A Icn at 400 V AC. For a 32 A breaker these are high-interrupting figures — the 36 kA at low voltage handles high-fault scenarios near a transformer, while the 10 kA at 400 V covers most industrial panel duties. The C-curve trips magnetically at 8 x In ±20 %, so it holds through motor inrush but clears fast on a hard short.
Mounts on DIN rail and occupies 8 x 9 mm pitches — 72 mm wide, 91 mm tall, 78.5 mm deep. The double terminals accept 1…35 mm² rigid or 1…25 mm² flexible; strip length 14 mm, torque to 3.5 N.m. Overvoltage category IV suits it for main incoming panels, not just sub-distribution.
