The A9F04313 is a 3-pole Acti9 iC60N miniature circuit breaker rated at 13 A with a C-curve (magnetic trip at 8 x In ±20 %). At 220-240 V AC the rating drops to 20 kA Icu, and at 380-415 V AC to 10 kA Icu, so verify your point-of-installation fault level against the voltage-dependent curve. The dual-standard certification (EN/IEC 60947-2 for industrial and EN/IEC 60898-1 for residential/commercial) means this breaker qualifies for both distribution board and industrial control panel applications — useful when a single BOM line must cover both environments. The thermal-magnetic trip unit provides overload protection via the bimetal strip and short-circuit protection via the solenoid, with no electronic components to fail.
At 54 mm wide (6 x 9 mm pitches), three of these occupy 162 mm of rail — plan your enclosure gland plate and wireway fill accordingly. That's enough cross-section for most 13 A feeder circuits without piggybacking. IP20 finger-safe terminals suit enclosed panel use only — no washdown rating. The toggle actuator and trip indicator give local visual status without needing to open the panel door.
The Acti9 iC60N family is Schneider's mainstream MCB platform, widely stocked and cross-referenced. If you need a different rating or pole count within the same family, the order-code pattern is consistent: A9F04xxx for 1P, A9F05xxx for 2P, A9F06xxx for 4P variants. No pin-compatible alternative from another manufacturer exists — the DIN-rail footprint is standard, but the terminal layout and accessory compatibility are Acti9-specific.
Durability and environmental specs
Rated for 10,000 electrical cycles and 20,000 mechanical cycles — sufficient for most distribution applications where the breaker operates infrequently (fault protection, not daily switching).
