The A9F03410 is a Schneider Acti9 iC60N miniature circuit breaker — 4 poles, B-curve, rated 10 A. It is a current-production part (lifecycle stage: current). The B-curve means magnetic tripping occurs at 4 x In ±20% (40 A nominal, 32–48 A window), suited for resistive or general-purpose loads where inrush is low — think lighting, heater banks, or control transformers. The 36 kA Icu at 12–133 V AC (EN/IEC 60947-2) is the maximum short-circuit current it can safely interrupt once; at 220–240 V that drops to 20 kA, and at 380–415 V to 10 kA. For a 400 V distribution board the IEC 60898-1 Icn is 6 kA — the more common rating for domestic/commercial final circuits.
Snaps onto DIN rail (mounting support: DIN rail). Occupies 8 x 9 mm pitches = 72 mm width. The 78.5 mm depth and 91 mm height are standard for the iC60 family — no gland-plate surprises. IP20 finger-safe front, pollution degree 3 (conductive pollution expected in industrial enclosures). Overvoltage category IV means it can be installed at the service entrance or main distribution board, not just downstream sub-panels.
Suitability for isolation confirmed under both standards — the contact position indicator shows open/closed state. The part carries CE marking for the EU market; UL/CSA listing is not stated in the evidence, so for North American projects verify local acceptance. RoHS and REACH compliance documentation is available from the manufacturer upon request — standard for Schneider's Acti9 range.
