The Schneider Electric A9F08425 is an Acti9 iC60H miniature circuit breaker rated for 25 A continuous current across four protected poles, with a D tripping curve that holds 12× In (±20 %) before the magnetic trip fires. The part is dual-rated to EN/IEC 60898-1 (domestic-grade Icn of 10 kA at 400 V AC) and EN/IEC 60947-2 (industrial-grade Icu up to 42 kA at 12-133 V AC), so it qualifies for both residential distribution boards and industrial panel builds.
Breaking capacity and isolation
The iC60H frame delivers 42 kA Icu at 12-133 V AC, 30 kA at 220-240 V AC, and 15 kA at 380-415 V AC per EN/IEC 60947-2. At 400 V AC the IEC 60898-1 Icn is 10 kA. The 4P version isolates all poles simultaneously, with a contact-position indicator and a trip-flag for local signalling.
IP20 finger-safe front. The thermal-magnetic trip unit is field-non-adjustable, so the 25 A rating is fixed; earth-leakage protection requires a separate Vigi block.
