It protects a 3-pole AC distribution circuit, and the D-curve magnetic trip at 12 x In (±20%) means it handles high inrush loads like small transformers or motor starters without nuisance tripping — the right call for a motor control panel or industrial machine supply. Snaps onto DIN rail (6 x 9 mm pitches), occupies 54 mm width. IP20 rated — panel-internal use, not washdown. Breaking capacity is 50 kA Icu at 220…240 V and 380…415 V AC per EN/IEC 60947-2, dropping to 25 kA at 440 V and 10 kA Icn at 400 V per EN/IEC 60898-1. That 50 kA rating at common industrial voltages gives solid SCCR headroom for a panel fed from a transformer of moderate size — you can coordinate downstream without cascading upstream. Rated insulation voltage 500 V AC, overvoltage category IV, pollution degree 3. Suitability for isolation confirmed to both standards — the toggle and contact position indicator give a visible air gap when off. Separate earth-leakage block can be added alongside if needed.","metaTitle":"Schneider Electric A9F05370 Acti9 iC60 D Curve MCB, 0.5 A 3P","metaDescription":"Schneider Electric A9F05370 Acti9 iC60 miniature circuit-breaker, D curve, 0.5 A, 3 poles, 50 kA breaking capacity, EN/IEC 60947-2, EN/IEC 60898-1.

The A9F05370 uses a D curve (12 x In magnetic trip) for high-inrush loads; a C-curve sibling (5 to 10 x In) would be the alternative for general-purpose distribution where inrush is lower.
