The Schneider Electric A9F08316 is an Acti9 iC60H miniature circuit breaker — 3-pole, 16 A rated current, D-curve trip characteristic, with a 42 kA breaking capacity at 12–133 V AC. It is a thermal-magnetic MCB (Category A per EN/IEC 60947-2) suited for distribution applications where high inrush currents from motor or transformer loads demand a D-curve magnetic trip at 12 x In (±20 %).
At 220–240 V AC it still holds 30 kA Icu, and at 380–415 V AC it manages 15 kA Icu.
Occupies 6 x 9 mm pitches (54 mm wide) — three poles at 18 mm per pole. Height 91 mm, depth 78.5 mm. Double terminals top and bottom accept 1–25 mm² rigid or 1–16 mm² flexible; tightening torque 2 N·m. Wire strip length 14 mm. IP20 finger-safe front. Overvoltage category IV (mains entry level).
Rated insulation voltage 500 V AC. Electrical durability 10,000 cycles; mechanical durability 20,000 cycles. Earth-leakage protection requires a separate Vigi block — not integrated. Local trip indicator and contact position indicator standard. White colour, toggle control.
