The Schneider Electric A9P62725 is a 25 A, 3P+N miniature circuit breaker from the Acti9 iC40 family, with a D tripping curve. The D curve means the magnetic trip fires at 10–14× In (250–350 A for this 25 A unit), making it the right choice for loads with a high inrush — think small motors, transformers, or banks of LED drivers where a B or C curve would nuisance-trip on startup. The thermal-magnetic element handles the overload side; the magnetic coil clears the short-circuit side. Breaking capacity is 4.5 kA Icn per EN/IEC 60898-1 and 6 kA Icu per EN/IEC 60947-2 at 400 V AC. That dual rating means it is tested to both the household-standard (60898) and the industrial-standard (60947) fault levels.
Panel integration — DIN rail fit and wiring
The 3P+N body takes 6 module pitches (9 mm each, so 54 mm wide). Neutral is on the left. The toggle gives ON/OFF plus a trip-indicator flag — no guessing whether it tripped or was switched off.
