For a 25 A distribution board fed from a transformer of typical impedance, 10 kA covers most commercial and light-industrial installations in IEC 60947-2 Category A. The DC rating matters for battery-backed or solar-combiner circuits — 6 kA at 250 V DC is not a universal match for every string combiner, but it is a real figure to check against your worst-case fault current. The Acti9 range is Schneider's current-generation DIN-rail MCB family, so the A9N4P25DIN is the standard production order code for a 25 A D-curve 4P breaker. ## Integration notes Mounts via clip-on to 35 mm DIN rail. Tightening torque 2 N·m.","metaTitle":"Schneider Electric A9N4P25DIN Acti9 xC60 MCB, 25 A D Curve,","metaDescription":"Schneider Electric A9N4P25DIN Acti9 xC60 miniature circuit breaker, 25 A rated current, D curve, 4 poles, 10 kA breaking capacity at 415 V AC.
