The Schneider Electric A9KF71106 is a 1-pole Acti9 K60 miniature circuit breaker rated 6 A with a C-curve, meaning magnetic tripping occurs between 5 and 10 times the rated current (30–60 A).
Snaps onto a standard DIN rail (35 mm) and occupies 2 x 9 mm pitches (18 mm wide) — one modular unit for a 1P breaker. Tunnel terminals accept 1–25 mm² rigid or 1–16 mm² flexible copper; strip length is 14 mm, torque to 2 N·m. Height is 81 mm, depth 70 mm — fits standard consumer unit and sub-distribution board cutouts.
Limitation class 3 (energy-limiting) per the same standard — it restricts let-through energy enough to protect downstream wiring and connected equipment during a short-circuit. Pollution degree 2 (non-conductive pollution only, occasional condensation), overvoltage category II (appliance / plug-connected loads). Operating altitude is 0–2000 m without derating.
