This is the part you spec into a distribution board when you need basic sinusoidal AC fault protection on a three-phase circuit with neutral. It is not for personnel protection — that calls for 30 mA or lower. The 4-pole body takes 8 module pitches at 18 mm per phase — 144 mm of rail width total. Tunnel-type terminals top and bottom accept 1 to 35 mm² rigid or 1 to 25 mm² flexible cable; strip 14 mm and torque to 3.5 N·m. Neutral is on the left. The toggle gives local ON/OFF/fault-trip indication, and there is a padlocking provision for lockout/tagout. IP20 rated — clean, dry indoor panel only, no washdown. Current production. This is not an obsolete or NRND line — the Acti9 xID range is Schneider's standard RCCB family for European and export markets. The part carries EN/IEC 61008-1 and EN/IEC 61008-2-1 certification, so it is accepted across most jurisdictions that adopt IEC standards. Same part, different passport — a genuine unit regardless of which authorized region it was sourced from.","metaTitle":"Schneider Electric A9N16256 Acti9 xID RCCB, 40 A, 300 mA, 4P","metaDescription":"Schneider Electric A9N16256 Acti9 xID RCCB, 40 A rated, 300 mA sensitivity, 4P, Type AC, 400-415 V AC, DIN rail mount.

The 40 A, 300 mA, 4P combination is the standard feeder-protection variant; no pin-compatible drop-in exists because the sensitivity and pole count change the part number."},{"question":"What is the A9N16256's depth?","answer":"The A9N16256 has a depth of 75 mm, with a width of 72 mm (8 module pitches at 18 mm per phase) and a height of 81 mm."},{"question":"What compliance standards does the A9N16256 meet?","answer":"The A9N16256 is certified to EN 61008-2-1, IEC 61008-2-1, and EN/IEC 61008-1.
