The C-curve means the magnetic trip operates between 5 and 10 times the rated current (5...10 x In per EN/IEC 60898-1, 8 x In ±20% per EN/IEC 60947-2), so it handles moderate inrush from motor starters or transformer banks without nuisance tripping, while still clearing hard faults fast. This breaker carries two breaking-capacity figures because it is certified to both the domestic (EN/IEC 60898-1) and industrial (EN/IEC 60947-2) standards. Under EN/IEC 60947-2 the ultimate breaking capacity (Icu) is 6 kA at 230 V AC; under EN/IEC 60898-1 the rated short-circuit capacity (Icn) is 4500 A at the same voltage. The limitation class is 3 (per EN/IEC 60898-1), meaning it limits let-through energy enough to protect downstream wiring in most domestic runs. Tunnel-type terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible; strip 14 mm and torque to 2 N.m. The toggle gives ON/OFF indication plus a separate trip indicator so you can tell at a glance whether it was manually switched or fault-tripped. IP20 on the body, IP40 inside a modular enclosure — fine for dry indoor panels, not for washdown zones.","metaTitle":"Schneider Electric A9P52640 Acti9 iC40 MCB, 40 A, 1P+N, C-Cu","metaDescription":"Schneider Electric A9P52640 Acti9 iC40 miniature circuit breaker, 40 A rated current, 1P+N, C-curve, 6 kA breaking capacity.
