The Schneider Electric A9KF71310BQ is a 3-pole miniature circuit-breaker from the Acti9 K60 series, rated 10 A with a C-curve magnetic trip characteristic (5–10 × In). It breaks 10 kA Icn at 415 V AC, 50/60 Hz, certified to EN/IEC 60898-1. Thermal-magnetic trip unit, no earth-leakage protection. This is the 6-module width (54 mm) version, set of 4 per package.
Limitation class 3 (energy let-through) limits downstream stress during a fault. Snaps onto standard DIN rail. The 54 mm width (6 × 9 mm pitches) fits a 3-pole breaker in a standard distribution board.
Within the Acti9 K60 family, the A9KF71310BQ is the 3-pole, 10 A, C-curve variant. The same physical footprint and breaking capacity is shared across the K60H range; the only variable is the rated current and curve choice. If the BOM requires a different amp rating or a B/D curve, the K60 line covers those — but the 3-pole 10 A C-curve is a common pick for general-purpose motor and lighting sub-circuits.
Pollution degree 2 (non-conductive, occasional condensation). Operating altitude to 2000 m, overvoltage category II. Electrical and mechanical durability both rated at 20,000 cycles.
