Breaking capacity is 10,000 A Icn at 240 V AC, 50/60 Hz, certified to EN/IEC 60898-1. The thermal-magnetic trip unit provides overload protection (thermal bimetal) and short-circuit protection (magnetic coil). Mounts on DIN rail via the fixed mounting support. Width is 18 mm (2 x 9 mm pitches), so a single-pole breaker occupies one module position in a distribution board. Tunnel terminals accept 1–25 mm² rigid or 1–16 mm² flexible copper; strip length is 14 mm, tightening torque 2 N.m. IP20 rated per IEC 60529 — finger-safe but not protected against moisture ingress, so it belongs inside an enclosure, not in a washdown or outdoor location. Pollution degree 2 (non-conductive dust, occasional condensation) is the standard for clean indoor panels.","metaTitle":"Schneider Electric A9KF21110BQ Acti9 K60 MCB, 10 A, B Curve,","metaDescription":"Schneider Electric A9KF21110BQ Acti9 K60 miniature circuit-breaker, 10 A rated current, B curve, 1-pole, 10 kA breaking capacity at 240 V AC.
