Breaking capacity is 10 kA Icn at 415 V AC 50/60 Hz per EN/IEC 60898-1 — enough for most commercial and light industrial sub-distribution boards where the upstream fault level stays under that threshold. C-curve means magnetic tripping occurs between 5 and 10 times In (125–250 A for this 25 A unit). Below 415 V the breaking capacity may be higher (check the coordination study for your specific supply voltage). Thermal-magnetic trip combines a bimetal strip for overload protection (time-delayed, inversely proportional to current) with a solenoid for instantaneous short-circuit response. Snaps onto DIN rail (EN/IEC 60715). Fixed mounting, toggle control. Width is 72 mm (8 x 9 mm pitches) — standard for a 4P MCB in the Acti9 family. Depth 70 mm, height 81 mm. Terminal tunnels accept 1–25 mm² rigid or 1–16 mm² flexible; strip 14 mm and torque to 2 N·m. IP20 finger-safe front, so it is fine inside a closed panel.","metaTitle":"Schneider A9KF71425BQ Acti9 K60 MCB, 4P C-curve 25 A, 10 kA","metaDescription":"Schneider Electric A9KF71425BQ Acti9 K60 miniature circuit-breaker, 4 poles, C-curve, 25 A rated current, 10 kA breaking capacity at 415 V AC.
