The Schneider Electric A9P52710 is an Acti9 iC40 miniature circuit-breaker rated 10 A with a C curve, configured 3P+N. The C curve (magnetic trip 5–10 × In per EN/IEC 60898-1, 8 × In ±20% per EN/IEC 60947-2) suits it for mixed resistive and moderate inductive loads — typical for general lighting and socket circuits in commercial or light industrial panels.
Breaking capacity and dual standard rating
This MCB carries two breaking-capacity ratings at 400 V AC: 4.5 kA Icn under EN/IEC 60898-1 (the domestic/light-commercial standard) and 6 kA Icu under EN/IEC 60947-2 (the industrial standard). The 4.5 kA Icn rating is the service breaking capacity for the 60898-1 duty cycle; the 6 kA Icu is the ultimate breaking capacity under 60947-2, and it also qualifies this breaker for isolation duty (marked 'suitable for isolation' per 60947-2).
The 3P+N unit occupies 6 x 9 mm pitches (54 mm total width).
Dual-certified to EN/IEC 60898-1 and EN/IEC 60947-2. Limitation class 3 per 60898-1, pollution degree 3 per 60947-2. IMQ quality label. The part carries an ON/OFF indication and a trip indicator on the toggle. Earth-leakage protection requires a separate block — not integrated.
