The A9F07410 is a 4-pole miniature circuit-breaker from the Acti9 iC60H family, rated 10 A with a C-curve trip characteristic. It's built for distribution panels where you need overcurrent protection on a 4-wire (3-phase + neutral) circuit. Breaking capacity is the headline: 42 kA Icu at 12-133 V AC, 30 kA at 220-240 V, 15 kA at 380-415 V, and 10 kA at 440 V (all per EN/IEC 60947-2). That's a high-interrupting rating for a 10 A MCB — it can clear a fault on a strong transformer-fed bus without welding its contacts. The 15 kA Icn at 400 V per EN/IEC 60898-1 is the standard domestic/commercial rating, but the 60947-2 figures give you the industrial SCCR headroom for panel coordination studies.
Snaps onto a DIN rail (mounting support: DIN rail per). It takes 8 modules of 9 mm pitch (72 mm wide), so plan your enclosure rail space accordingly — that's a 4-pole breaker in a standard 72 mm footprint. Height is 91 mm, depth 78.5 mm; the toggle and trip indicator are on the front face.
Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/commercial). That means it qualifies as a circuit-breaker for isolation (suitability for isolation: yes per both standards). Pollution degree 3, overvoltage category IV — rated for the harsh electrical environment at the service entrance or main distribution board.
