The A9P52732 is a 32 A, C-curve miniature circuit breaker from the Acti9 iC40 series, wired 3P+N. The C curve (5–10× In magnetic trip) suits general-purpose distribution loads — lighting banks, small motor circuits, socket outlets — where inrush is moderate. The 4.5 kA Icn at 400 V AC (EN/IEC 60898-1) is the service breaking capacity for the MCB standard; the 6 kA Icu (EN/IEC 60947-2) is the ultimate breaking capacity under the industrial standard, giving you SCCR headroom for panel coordination studies. Dual-rated to both standards means this part qualifies for residential/commercial (60898-1) and industrial (60947-2) installations without a separate part number.
Clip-on mounting to DIN rail (35 mm per EN 60715). At 54 mm wide (6 x 9 mm pitches) and 85 mm tall, it occupies a standard 3P+N modular slot. Depth of 74 mm leaves clearance for front-panel doors or gland plates. Tunnel terminals accept 1–16 mm² rigid or 1–10 mm² flexible; strip 14 mm and torque to 2 N·m.
