The Schneider Electric A9KF71116BQ is a 1-pole miniature circuit-breaker from the Acti9 K60 series, rated 16 A with a C curve and a breaking capacity of 10 kA Icn at 240 V AC, 50/60 Hz, per EN/IEC 60898-1.
Mounts on a standard DIN rail (35 mm) — the 18 mm width (2 x 9 mm pitches) fits a single-module slot in any Acti9 or third-party enclosure. The tunnel terminals accept 1–25 mm² rigid or 1–16 mm² flexible conductors, with a wire-stripping length of 14 mm and a tightening torque of 2 N·m. That's a solid grip for 6 mm² or 10 mm² feed conductors common in final distribution circuits.
Durability and environment
Rated for 20,000 electrical and 20,000 mechanical cycles — enough for frequent switching in lighting or small motor circuits. The IP20 finger-safe terminals suit enclosed panel installation; tropicalisation class 2 per IEC 60068-1 handles 95 % relative humidity at 55 °C, so it holds up in hot, humid plant environments without internal corrosion. Pollution degree 2 (non-conductive dust, occasional condensation) is the standard for clean commercial and light industrial panels.
Certified to EN/IEC 60898-1 for overcurrent protection in household and similar installations. Suitable for isolation per that standard — confirmed by the manufacturer.
