The Schneider Electric A9F06610 is an Acti9 iC60H miniature circuit breaker with a B curve, rated 10 A, 1P+N, and a breaking capacity of 42 kA Icu at 12-60 V AC. The thermal-magnetic trip unit provides overcurrent and short-circuit protection, with magnetic tripping at 4 x In +/- 20 %.
The B curve (magnetic trip at 4 x In) means this MCB is suited for resistive or general-purpose loads with low inrush — common in lighting, socket circuits, and control transformers. The 10 A rating handles branch circuits up to that continuous current. The 42 kA Icu at 12-60 V AC is the ultimate breaking capacity under EN/IEC 60947-2; at 230 V AC the Icn under EN/IEC 60898-1 is 10000 A. The 1P+N configuration switches the phase and provides a switched neutral, with the neutral on the left side.
