It's certified to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/light commercial), so it qualifies for isolation duty per both standards. ## Deployment and integration Snaps onto a DIN rail — 36 mm wide, 4 x 9 mm pitches, 91 mm tall, 78.5 mm deep. The double terminals on top and bottom accept 1–35 mm² rigid or 1–25 mm² flexible, with a 14 mm strip length and 3.5 N·m tightening torque. Overvoltage category IV suits it for the main distribution board, not just sub-panels.","metaTitle":"Schneider Electric A9F05250 Acti9 iC60N MCB, D Curve 50 A 2P","metaDescription":"Schneider Electric A9F05250 Acti9 iC60N miniature circuit-breaker, D curve, 50 A, 2 poles, 36 kA breaking capacity.

Submit an RFQ for current availability and pricing — confirmed at quote time, no stock or price figures published here."},{"question":"What does the D curve mean on this MCB?","answer":"The D curve sets the magnetic trip threshold at 12 x In ±20% — for a 50 A breaker, that's roughly 480–720 A instantaneous trip. It's designed for loads with high inrush like motors, transformers, and welding equipment, where a B or C curve would nuisance-trip on startup."},{"question":"What breaking capacity does the A9F05250 have at 400 V?","answer":"At 380–415 V AC the Icu is 10 kA per EN/IEC 60947-2; the Icn at 400 V per EN/IEC 60898-1 is 6 kA.
