The Schneider Electric A9F05110 is an Acti9 iC60N miniature circuit breaker — a 1-pole, 10 A thermal-magnetic MCB with a D tripping curve. It's built for distribution duty in a 2-module (18 mm per pole) DIN-rail footprint, so it slots straight into a standard panel enclosure alongside other Acti9 kit.
Breaking capacity — what it means on the line
This breaker carries dual-standard ratings: 36 kA Icu at 12…60 V AC and 10 kA Icu at 220…240 V AC per IEC 60947-2, plus 6 kA Icn at 230 V AC per IEC 60898-1. The 36 kA figure covers low-voltage AC distribution where fault current can spike — think panel feeds close to a transformer. On the DC side, it's rated 15 kA Icu at 12…60 V DC and 10 kA at 60…72 V DC — useful for DC distribution in telecom shelters or control cabinets where battery-backed 48 V loops need short-circuit protection.
Snaps onto a DIN rail (35 mm symmetrical rail per EN 60715).
