The D curve means the magnetic trip operates between 10 and 14 times the rated current (10–14 x In per EN/IEC 60898-1, and 12 x In ±20% per EN/IEC 60947-2). The 40 A continuous rating handles the steady-state draw; the D curve clears only hard faults. Breaking capacity is dual-rated: 10 kA Icu at 400 V AC per EN/IEC 60947-2, and 6 kA Icn at 400 V AC per EN/IEC 60898-1. The 6 kA Icn is the domestic/residential rating. ## Dual standard compliance and isolation suitability This MCB carries both EN/IEC 60898-1 (domestic/residential) and EN/IEC 60947-2 (industrial) certifications. That dual rating simplifies specification: the same part meets the requirements for a building-services distribution board and an industrial control panel. ## Mounting and integration — DIN rail clip-on The 54 mm width (6 x 9 mm pitches) fits a standard modular enclosure slot. Terminals are tunnel type, accepting 1–16 mm² rigid or 1–10 mm² flexible copper, with a tightening torque of 2 N.m. IP20 on the terminals, IP40 inside the modular enclosure.","metaTitle":"Schneider Electric A9P64740 Acti9 iC40N MCB, D Curve, 40 A,","metaDescription":"Schneider Electric A9P64740 Acti9 iC40N miniature circuit breaker, 40 A, D curve, 3P+N, 10 kA Icu at 400 V AC.
