The A9N2P40DGN is a Schneider Electric Acti9 xC60 miniature circuit breaker — 40 A rated, D curve, 2 poles, with a 10 kA breaking capacity at 240 V and 415 V AC per IS/IEC 60898-1. The thermal-magnetic trip unit handles the overload side; the magnetic coil clears the short-circuit side.
Integration notes
The 36 mm width (4× 9 mm pitches) fits a 2-pole breaker in a compact footprint. Terminals accept up to 35 mm² rigid or 25 mm² flexible; strip 13 mm and torque to 3.5 N·m. IP20 finger-safe front, pollution degree 3 — fine for most industrial control cabinets. The toggle gives ON/OFF indication, and the contact position indicator confirms the state visually.
