Breaking capacity is 10 kA Icu at 400 V AC per EN/IEC 60947-2, and 6000 A Icn at 400 V AC per EN/IEC 60898-1. Dual-rated to both EN/IEC 60898-1 (domestic / commercial MCB standard) and EN/IEC 60947-2 (industrial circuit-breaker standard), so it qualifies for either a distribution board or an industrial control panel. Pollution degree 3 per 60947-2 means it's rated for the conductive-dust and condensation environment inside a typical unsealed enclosure. ## DIN-rail integration and terminal details The 3-pole body occupies 6 × 9 mm pitches — 54 mm total width — so it fills six module positions on the rail. Strip length 14 mm. IP20 finger-safe on the front face; IP40 inside the modular enclosure. Not rated for washdown — keep this inside a cabinet, not on the machine surface. Carries OVE (Austria) and AENOR (Spain) quality labels. Dual-standard certified to EN/IEC 60898-1 and EN/IEC 60947-2. Suitability for isolation confirmed per EN/IEC 60947-2 — the toggle and contact-position indicator give a visible break for safe isolation during maintenance. Electrical and mechanical durability both rated at 20,000 cycles.","metaTitle":"Schneider Electric A9P54320 Acti9 iC40N MCB, 20 A, 3P, C-Cur","metaDescription":"Schneider Electric A9P54320 Acti9 iC40N miniature circuit breaker, 20 A, 3-pole, C-curve, 10 kA Icu at 400 V AC.
