The Schneider Electric A9F03716 is an Acti9 iC60N miniature circuit-breaker (MCB) rated at 16 A, curve B, in a 3P+N (three-pole plus neutral) format. It is a thermal-magnetic trip device designed for distribution circuits in commercial and industrial panels. Its breaking capacity spans 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V AC, 10 kA at 380–415 V AC, and 6 kA at 440 V AC per EN/IEC 60947-2, plus a 6000 A Icn at 400 V AC per EN/IEC 60898-1. That dual rating means it qualifies for both industrial (60947-2) and residential/commercial (60898-1) applications — a single part number covers both compliance paths.
The 3P+N format places the neutral pole on the left, with the three phase poles to its right. Double terminals top and bottom accept 1–25 mm² rigid or 1–16 mm² flexible cable; torque to 2 N·m. IP20 rated, so it belongs inside an enclosure — not exposed to washdown or outdoor weather.
