The A9F08432 is a 4-pole Acti9 iC60H miniature circuit breaker rated 32 A with a D tripping curve (12 x In magnetic trip limit). The D curve means it tolerates the high inrush of motor or transformer loads without nuisance tripping — the magnetic trip operates at 12 x In, so a 32 A breaker holds through the starting surge of a 7.5 kW motor on a 400 V line and clears a hard short. The 42 kA Icu at 12–133 V AC and 30 kA at 220–240 V AC (per EN/IEC 60947-2) give headroom for high-fault panels; the 15 kA Icu at 380–415 V AC and 10 kA at 440 V AC cover most European industrial distribution. It also carries a 10 kA Icn at 400 V AC under EN/IEC 60898-1 for domestic/commercial branch circuits. Dual-rated to both standards — you can spec it for IEC 60947-2 industrial duty or IEC 60898-1 residential/commercial, whichever your panel design calls for. The thermal-magnetic trip unit handles overload (thermal bimetal) and short-circuit (magnetic solenoid) in one package. IP20 finger-safe terminals — fine inside a closed cabinet, not for wet environments.
Snaps onto standard DIN rail (mounting support: DIN rail). Occupies 8 x 9 mm pitches (72 mm wide) — four pole modules side by side. Depth 78.5 mm, height 91 mm. Tightening torque 3.5 N.m. Wire strip length 14 mm. The toggle actuator and trip indicator give local status without opening the door.
