For a panel builder or MRO planner, that means one 36 mm-wide DIN-rail module replaces a separate MCB and AFDD unit, saving four module pitches of enclosure space and reducing wiring complexity.
This AFDD carries dual breaking capacity ratings because it's certified to two standards. Under EN/IEC 60898-1 (the MCB standard for household and similar installations) it's rated 6,000 A Icn at 230 V AC, with a higher short-circuit rating of 10,000 A Icu under EN/IEC 60947-2 (the industrial CB standard). The 3,000 A Icn1 rating is a reduced value for specific conditions per the standard.
Depth is 73 mm, height 91 mm — standard for a 1P+N module in the Acti9 family. Tunnel-type terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible; wire strip length 14 mm, tightening torque 2 N.m. Cable entry from top and bottom. Neutral on the left.
Environmental and quality marks
Tropicalisation severity B per IEC 60068-2-30 for 28 days — the unit handles damp heat cycling typical of non-condensing environments. OVE quality label (Austrian mark). Pollution degree 2 (normal, non-conductive pollution). Operating altitude up to 2,000 m. Electrical and mechanical durability rated at 20,000 cycles each.
