The A9F08410 is a 4-pole D-curve miniature circuit breaker from the Schneider Acti9 iC60H family, rated 10 A. The 42 kA Icu at 12-133 V AC (EN/IEC 60947-2) is the maximum fault current it can safely interrupt once; the 15 kA Icu at 380-415 V AC and 10 kA Icn at 400 V (EN/IEC 60898-1) govern the real-world installation. Dual-rated to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/commercial), so it qualifies for distribution panels and motor control centres alike.
Deployment context
IP20 finger-safe front; no washdown rating, so keep it inside the enclosure. The separate earth-leakage block (Vigi iC60) clips on the right side if you need RCD protection; the breaker itself is thermal-magnetic only.
