The A9F04406 is a 6 A, C-curve, 4-pole miniature circuit-breaker from the Schneider Electric Acti9 iC60N range. At 400 V AC, the Icn is 10 kA per EN/IEC 60898-1; the Icu per EN/IEC 60947-2 reaches 36 kA at 12-133 V AC, 20 kA at 220-240 V, 10 kA at 380-415 V, and 6 kA at 440 V. The 4-pole configuration with 4 protected poles and a separate earth-leakage block option makes it appropriate for three-phase plus neutral distribution in panelboards where isolation is required — the breaker is marked suitable for isolation per both standards.
Mounts on DIN rail (9 mm pitch, 8 pitches wide = 72 mm). The thermal-magnetic trip unit is sealed; no field adjustment. Wire stripping length is 14 mm. IP20 finger-safe terminals. The white housing includes a trip indicator and contact position indicator.
