The Schneider Electric A9F68332 is a 3-pole Acti9 iT60 miniature circuit breaker rated 32 A with a C curve, designed for distribution panels on DIN rail. It carries dual certification to EN/IEC 60898-1 and EN/IEC 60947-2, so it qualifies for both residential and industrial branch-circuit protection — the 60947-2 rating matters when the SCCR study calls for Category A utilization.
Breaking capacity and trip characteristics
Breaking capacity varies with voltage: 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V, 10 kA at 380–415 V, and 6 kA at 440 V (all per EN/IEC 60947-2). Under the domestic standard (EN/IEC 60898-1) it delivers 10 kA Icn at 400 V. The C curve magnetic trip is fixed at 8 x In ±20 %, meaning the instantaneous trip starts between 256 A and 384 A — typical for motor and lighting circuits with moderate inrush.
Physical integration and environment
Width is 54 mm (6 x 9 mm pitches), so it fills three standard DIN-rail module positions. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible copper; strip length 14 mm, torque 3.5 N·m. IP20 B finger-safe front, pollution degree 3, and tropicalisation class 2 per IEC 60068-2-78 (95 % RH). Operating temperature range -35 to 70 °C, storage -40 to 85 °C, altitude limit 2000 m.
