The A9F08302 is a Schneider Electric Acti9 iC60H miniature circuit-breaker, a 3-pole unit rated at 2 A with a D tripping curve. The thermal-magnetic trip unit handles the overload side; the magnetic element clears short-circuits. For a 2 A rating, this holds the unit on the grid for steady-state loads up to 2 A and trips fast on a fault, provided the prospective short-circuit current stays within the 70 kA Icu envelope at 415 V.
The iC60H designation means this breaker sits in the high-breaking-capacity tier of the Acti9 iC60 family. At 380…415 V AC the Icu is 70 kA; at 440 V it drops to 50 kA, and at 400 V the Icn (service breaking capacity per EN/IEC 60898-1) is 10 kA. For a panel designer coordinating downstream MCBs, the 70 kA Icu figure gives headroom for high-fault installations — large distribution transformers or industrial switchboards — provided the upstream protective device limits let-through energy to what the 2 A D-curve can withstand. The limitation class is 3 per EN/IEC 60898-1, meaning it restricts peak let-through current and I²t, which helps with cascading and reduces arc-flash energy on the load side.
Mounts on DIN rail — the 9 mm pitch count is 6, so the breaker occupies 6 modules (54 mm). IP20 finger-safe front. The toggle control has a trip indicator that shows a red flag when the breaker has tripped on fault — useful for a field-service tech walking a panel to find which circuit dropped. Stripping length is 14 mm; torque the terminals to 2 N·m.
