The A9F08313 is a 13 A D-curve miniature circuit breaker from the Acti9 iC60H series, 3-pole, rated for both AC and DC networks. The D curve means magnetic tripping occurs at 12 x In (156 A) with a +/-20% tolerance — so it handles the inrush of motor loads, transformers, or capacitive banks without nuisance trips on start-up. The 42 kA Icu at 12-133 V AC (EN/IEC 60947-2) is its ultimate breaking capacity; at 220-240 V AC that drops to 30 kA, and at 380-415 V AC to 15 kA. At the distribution-board voltage of 400 V AC, the Icn per EN/IEC 60898-1 is 10 kA — the figure that governs residential and light commercial panel coordination. The thermal-magnetic trip unit covers overload (thermal bimetal) and short-circuit (solenoid) in one package, with a separate earth-leakage block available if needed.
Depth is 78.5 mm, height 91 mm — check gland-plate clearance if the enclosure is shallow.
Lifecycle stage is current — no end-of-life notice on record. For a BOM freeze or line-down spare, the 13 A D-curve in 3P is a standard catalogue item, so supply continuity is predictable. No official successor exists because none is needed.
Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (residential/ commercial) — covers both the panel builder's coordination study and the final installation standard. Suitability for isolation confirmed under both standards. Contact position indicator and trip indicator give visual confirmation without opening the panel.
