Product details

The Schneider Electric A9KF21110BQ is an Acti9 K60 miniature circuit-breaker (MCB) rated at 10 A with a B tripping curve, in a 1-pole format.

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.
