Acti9 iC40 MCB, D Curve, 6 A, 3P+N
The Schneider Electric A9P62706 is an Acti9 iC40 miniature circuit breaker with a D tripping curve, rated 6 A, 3P+N poles. The D curve's magnetic trip threshold of 10–14 x In (12 x In ±20% per EN/IEC 60947-2) means it tolerates the starting surge of inductive equipment without nuisance tripping — a common requirement in industrial panel builds.
Breaking Capacity and Standards Compliance
Rated breaking capacity is 4500 A Icn at 400 V AC per EN/IEC 60898-1 for general distribution, and 6 kA Icu at 400 V AC per EN/IEC 60947-2 for industrial isolation duty. This dual rating lets the part serve both residential/commercial (60898-1) and industrial (60947-2) installations from the same SKU.
Height 85 mm, depth 74 mm. Tunnel terminals accept 1–10 mm² flexible or 1–16 mm² rigid wire; strip length 14 mm, tighten to 2 N.m. Neutral is on the left. IP20 finger-safe on the front, IP40 inside a modular enclosure. The 3P+N configuration with three protected poles and a switched neutral is standard for three-phase distribution boards where the neutral is not overload-protected but is switched with the phases.
