The Schneider Electric A9N3P10DGN is a 10 A D-curve miniature circuit breaker from the Acti9 xC60 range, 3-pole, rated for 220...240 V AC and 380...415 V AC at 50/60 Hz. Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, certified to IS/IEC 60898-1. The D-curve magnetic trip operates at 10...14 x In, so it holds through the high inrush of motor or transformer loads without nuisance tripping. Thermal-magnetic trip unit — standard for overload and short-circuit protection.
Width is 54 mm (6 x 9 mm pitches), depth 77.5 mm, height 85 mm. Tightening torque 2 N.m. Rated for 20,000 electrical and 20,000 mechanical cycles — covers typical panel life in commercial buildings. Separate earth-leakage block available if needed.
