At 230 V AC, the Icn (rated short-circuit capacity per EN/IEC 60898-1) is 6000 A — the value used for domestic and similar installations. Under IEC 60947-2, the Icu (ultimate breaking capacity) reaches 10 kA at 230...240 V AC, which is the figure an industrial panel designer references for SCCR coordination. Dual certification means the same unit satisfies both a residential distribution board spec and a control-panel short-circuit rating, simplifying BOM consolidation. The 18 mm width per pole — two 9 mm pitches — keeps the 1P+N assembly at 18 mm total, fitting standard distribution board spacing.","metaTitle":"Schneider Electric A9N21364 DT40N MCB, 6 A, 1P+N, Curve C, 6","metaDescription":"Schneider Electric A9N21364 DT40N MCB, 6 A rated, 1P+N, curve C, 6 kA (Icn) / 10 kA (Icu) breaking capacity.
