The 63 A rated current and C-curve magnetic trip (5–10 x In) make it a standard choice for general-purpose distribution and moderate motor-starting loads — the C-curve holds through the inrush of small motors and transformers without nuisance tripping, but clears fast enough on a hard short. On a DIN rail, 36 mm wide — two modules — it fits a standard enclosure with 4 pitches at 9 mm. ## Integration details The IP20 finger-safe front is standard for enclosed panels — not for wet or outdoor locations without a secondary enclosure.","metaTitle":"Schneider Electric A9KF71263BQ Acti9 K60 MCB, 63A 2P C-Curve","metaDescription":"Schneider Electric A9KF71263BQ Acti9 K60 miniature circuit breaker, 63 A rated, 2 poles, C-curve, 10 kA breaking capacity at 415 V AC.
