The A9F75313 is a Schneider Acti9 iC60N miniature circuit breaker — 3-pole, 13 A rated current, D trip curve. The 36 kA Icu at 12-133 V AC (EN/IEC 60947-2) is the maximum fault current it can safely interrupt at that voltage range; at 220-240 V that drops to 20 kA, and at 380-415 V to 10 kA — still enough for most distribution panels behind a transformer. Dual-rated to both EN/IEC 60898-1 (the MCB standard) and EN/IEC 60947-2 (the industrial breaker standard), so it qualifies for either residential or industrial duty. Thermal-magnetic trip means the thermal bimetal handles overloads (slow, inverse-time), and the solenoid handles short circuits (instantaneous). IP20 finger-safe terminals, so it's fine inside an enclosure but not for wet locations.
Dual-certified to EN/IEC 60898-1 (the household/ similar installation MCB standard) and EN/IEC 60947-2 (the low-voltage switchgear and controlgear standard for industrial applications). This dual rating is the key differentiator from a purely domestic MCB — it means the breaker is tested and marked for both duty classes, so it can be specified into an industrial panel without a separate industrial-grade breaker. Suitability for isolation is confirmed under both standards — you can safely use it as a disconnecting means.
