Dual-rated to both EN/IEC 60898-1 (household-type MCB) and EN/IEC 60947-2 (industrial circuit breaker) standards, so it qualifies for either duty. The 60947-2 rating is what matters for industrial control panels where SCCR coordination is required — the 10 kA Icu figure is the one an inspector or panel builder will look for on the nameplate. ## Where it goes in a panel The 3P+N configuration (three protected poles plus a switched neutral on the left) fits European-style distribution boards where the neutral is switched alongside the phases. Terminals accept 1–16 mm² rigid or 1–10 mm² flexible — enough for a 25 A feed with some headroom. IP20 on the body (finger-safe), IP40 inside a modular enclosure. The Acti9 iC40N series is a standard catalog item from Schneider, widely specified in European and Middle Eastern distribution projects.","metaTitle":"Schneider Electric A9P54725 Acti9 iC40N MCB, 25 A, C Curve,","metaDescription":"Schneider Electric A9P54725 Acti9 iC40N miniature circuit breaker, 25 A rated current, C curve, 10 kA breaking capacity at 400 V AC.

If you need a higher short-circuit rating in the same footprint, that's the sibling to look at. No pin-compatible drop-in exists outside the series — the DIN-rail pitch and terminal layout are common across the range, so swapping is straightforward if the panel SCCR allows."},{"question":"Where can I buy the A9P54725?","answer":"Sourced and quoted to order against an RFQ through independent industrial distribution.
