The Schneider Electric A9K24710 is an Acti9 iK60N miniature circuit-breaker (MCB) — a 3P+N unit rated at 10 A with a C-curve trip characteristic.
At 10 A it handles a 2.3 kW resistive load on 230 V single-phase or roughly 6.9 kW across three phases. The 3P+N configuration protects three poles and switches the neutral; the neutral sits on the left. Thermal-magnetic trip technology covers both overload (thermal) and short-circuit (magnetic) events. Limitation class 3 means it limits fault energy effectively — less stress on downstream wiring and equipment. Pollution degree 2 (non-conductive pollution only) and overvoltage category III (distribution level) are typical for fixed-installation MCBs. Wire strip length 14 mm.
