It's a thermal-magnetic MCB built to dual standards — EN/IEC 60947-2 for industrial use and EN/IEC 60898-1 for residential/commercial — so it fits distribution boards and panel schedules where both certifications matter. The 42 kA figure at low voltage means it can handle serious fault currents upstream without letting an arc cascade through the panel. The C-curve (magnetic trip at 8 x In ±20%) means this breaker holds through moderate inrush — typical for lighting banks, small transformers, and motor control circuits where the start-up surge doesn't exceed about 160 A before the magnetic trip clears a hard short. At 400 V AC, the Icn (rated short-circuit capacity per EN/IEC 60898-1) is 10 kA, while the Icu per 60947-2 is 15 kA at 380–415 V and 10 kA at 440 V. That 15 kA at 400 V-class voltages is enough for most sub-distribution panels fed by a 500 kVA transformer; if your available fault current is higher, step up to the iC60L or a molded-case breaker. The IP20 finger-safe terminals accept 1–25 mm² rigid or 1–16 mm² flexible wire, double-terminals top and bottom for daisy-chaining feed-through. The toggle handle and trip indicator give a clear visual on the panel front.","metaTitle":"Schneider Electric A9F07420 Acti9 iC60H MCB, 20A 4P C-Curve","metaDescription":"Schneider Electric A9F07420 Acti9 iC60H miniature circuit breaker, 20 A rated, 4 poles, C-curve, 42 kA breaking capacity.
