The Schneider Electric A9P62710 is an Acti9 iC40 miniature circuit breaker rated at 10 A with a D curve, configured 3P+N. Breaking capacity is 4.5 kA Icn per EN/IEC 60898-1 and 6 kA Icu per EN/IEC 60947-2 at 400 V AC — dual-rated so it fits both residential distribution boards (60898-1) and industrial panel schedules (60947-2) without a separate derating calculation.
D-curve trip behaviour
The D curve's magnetic trip fires between 10 and 14 times In per EN/IEC 60898-1, and at 12 x In ±20 % per EN/IEC 60947-2. That high inrush tolerance is sized for motor circuits, transformer primaries, and welding equipment — loads that draw a short-duration surge well above running current without nuisance tripping.
Tightening torque 2 N·m top or bottom. Wire strip length 14 mm. IP20 finger-safe on the front; IP40 inside a modular enclosure. Padlocking device compatible for lockout/tagout.
Certified to EN/IEC 60898-1 and EN/IEC 60947-2. Pollution degree 3 per 60947-2. Suitability for isolation marked. Operating altitude 2000 m, relative humidity 95 % at 55 °C. Earth-leakage protection via separate block (not integral).
