The Schneider Electric A9KF71110BQ is an Acti9 K60 miniature circuit-breaker rated 10 A, single-pole, with a C-curve trip characteristic and a 10 kA Icn breaking capacity at 240 V AC (EN/IEC 60898-1). It is a thermal-magnetic MCB for distribution boards — the C curve means it trips magnetically between 5 and 10 times rated current (50–100 A), so it handles moderate inrush from lighting or small motor loads without nuisance tripping.
At 18 mm width (2 x 9 mm pitches), it occupies a single module slot — no extra space needed for neutral switching since this is a 1P breaker protecting only the phase. Tunnel terminals accept up to 25 mm² rigid or 16 mm² flexible conductors; tightening torque is 2 N.m top or bottom. The IP20 finger-safe terminals are fine for enclosed distribution boards.
