The A9P64710 is a 3P+N miniature circuit breaker from the Schneider Acti9 iC40N line, rated 10 A with a D tripping curve. The 10 kA Icu at 400 V AC (per EN/IEC 60947-2) tells you it can safely interrupt a fault up to that level without welding contacts or cascading upstream; the 6 kA Icn per EN/IEC 60898-1 is the domestic/light-commercial rating. For a panel builder, the 3P+N configuration protects three phases plus switches the neutral, common in three-phase distribution boards where you want the neutral isolated on the same handle.
Clip-on mount to standard DIN rail, 6 module pitches wide (54 mm per).
Production status is current per the manufacturer — this part is still in the active catalog. No end-of-life notice on record. If you're holding a legacy board that specified this exact order code, it's still a clean drop-in — no last-time-buy scramble needed.
Dual-certified to EN/IEC 60898-1 (domestic MCB standard) and EN/IEC 60947-2 (industrial breaker standard), which means it qualifies for both residential distribution boards and industrial panel schedules. Carries OVE and AENOR quality marks — accepted in Central European and Spanish markets. Pollution degree 3 per 60947-2, so it's rated for conductive environments typical in industrial enclosures.
