The A9KF71202BQ is a 2-pole miniature circuit breaker from the Schneider Electric Acti9 K60 series, rated 2 A with a C trip curve and a 10 kA breaking capacity at 415 V AC per EN/IEC 60898-1. It uses thermal-magnetic trip technology, with magnetic tripping between 5 and 10 times the rated current (5...10 x In), so it handles moderate inrush from lighting or small motor loads without nuisance trips. Rated for a 50/60 Hz AC network, it snaps onto a DIN rail and occupies 4 module pitches (36 mm wide) in the panel — a standard 2P width for distribution boards.
The 10 kA Icn at 415 V AC is the short-circuit breaking capacity the breaker can safely interrupt under standard conditions per EN/IEC 60898-1 — enough for most commercial and light industrial distribution boards where the prospective fault current stays below that level. Terminals accept up to 25 mm² rigid or 16 mm² flexible conductors, and the tightening torque is 2 N.m for both top and bottom connections — standard for this class, no special tooling needed. IP20 finger-safe protection on the front, but the terminals are exposed once wired — standard for panel-mounted MCBs.
