Schneider Electric A9F08113 is a 1-pole Acti9 iC60H miniature circuit breaker rated 13 A with a D tripping curve (12 x In magnetic trip limit, +/- 20 %). It breaks up to 42 kA Icu at 12-60 VAC 50/60 Hz per EN/IEC 60947-2, and 10 kA Icn at 230 VAC per EN/IEC 60898-1. Dual-rated to both standards, so it fits distribution boards (60898-1) and industrial panel feeders (60947-2) in the same slot.
D curve and breaking capacity
The D curve trips magnetically at 12 x In (156 A typical), which avoids nuisance trips on transformer inrush or motor starting — common on DC supply or AC drives with high capacitive charge. DC breaking capacity is 20 kA Icu at 12-60 VDC, 15 kA at 60-72 VDC, making it usable on 48 V battery banks or DC bus distribution. Rated insulation voltage is 500 VAC; overvoltage category IV suits main-panel incoming feeders. Pollution degree 3 (conductive pollution) means it holds up in industrial enclosures without conformal coating.
DIN-rail footprint and wiring
Terminals accept 1-25 mm² rigid or 1-16 mm² flexible, double terminal top and bottom for daisy-chaining. Torque to 2 N·m; strip 14 mm. IP20 finger-safe front, but the terminals need enclosure protection in wet areas.
