The A9F05410 is a 4-pole (4P) miniature circuit-breaker from the Acti9 iC60N series, rated 10 A with a D-curve — magnetic trip at 12 x In (±20 %), so it handles inrush from motor loads, transformers, or welding equipment without nuisance tripping on startup. The thermal-magnetic trip unit covers both overload (thermal bimetal) and short-circuit (solenoid) protection in one package. Breaking capacity hits 36 kA Icu at 12–133 V AC (EN/IEC 60947-2), enough for high-fault panels near substations; derates to 20 kA at 220–240 V, 10 kA at 380–415 V, and 6 kA at 440 V. Under EN/IEC 60898-1 it's rated 10 kA Icn at 400 V — the standard for domestic/commercial distribution boards. That dual-standard certification (60947-2 for industrial, 60898-1 for distribution) means it qualifies for either a control-panel feeder or a sub-distribution board.
Snaps onto standard DIN rail — 9 mm pitch occupies 8 modules (72 mm wide), which is the space footprint to budget in your enclosure layout. Double terminals top and bottom accept 1–25 mm² rigid or 1–16 mm² flexible; strip 14 mm and torque to 2 N·m.
