The Schneider Electric A9P64325 is an Acti9 iC40N miniature circuit breaker rated 25 A, 3-pole, with a D tripping curve. It carries a 10 kA breaking capacity (Icu) at 400 V AC per EN/IEC 60947-2 and 6 kA Icn per EN/IEC 60898-1. The D curve's magnetic trip threshold is 10–14 × In (EN/IEC 60898-1) or 12 × In ±20% (EN/IEC 60947-2), so it's sized for high-inrush loads like motor feeders or transformer primaries where a C curve would nuisance-trip.
Clip-on mounting to DIN rail, 54 mm wide (6 × 9 mm pitches). Tunnel terminals accept 1–10 mm² flexible or 1–16 mm² rigid; tighten to 2 N·m. IP20 finger-safe terminals, IP40 in modular enclosure.
Lifecycle stage is current — this is a production part in the Acti9 range, not subject to phase-out.
