The Schneider Electric A9F08250 is a 50 A, 2-pole miniature circuit breaker from the Acti9 iC60H series, built for distribution panels where high inrush loads — motor starters, transformers, discharge lighting — demand a D tripping curve. The D curve means magnetic tripping occurs at 12 x In ±20 % (600 A instantaneous), so it passes the starting surge of a motor or a capacitor bank without nuisance tripping, then clears a hard short fast. Dual-rated to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/similar), this part carries a 42 kA Icu at 12-133 V AC and 15 kA Icu at 380-415 V AC — the 60947-2 rating is the one that governs its use in an industrial panel where fault current can hit those levels.
The 36 mm width (4 x 9 mm pitches) is the standard 2-module footprint for a 2-pole MCB — no surprise for the panel builder laying out a distribution board. Depth is 78.5 mm, height 91 mm. Terminals accept 1-35 mm² rigid or 1-25 mm² flexible, double terminal top and bottom, with a tightening torque of 3.5 N.m. Wire stripping length is 14 mm.
What compliance documentation covers this part
The manufacturer provides a declaration of conformity covering these standards; RoHS and REACH compliance is standard for Schneider's Acti9 range, though the specific statement is not in this spec excerpt. For a PO trace or nameplate check, the device short name is iC60H, the range is Acti9.
