The A9F68120 is a 20 A, 1-pole miniature circuit breaker from the Schneider Acti9 iT60 series, built for distribution panels where the C-curve handles moderate inrush — motor starters, small transformers, capacitor banks — without nuisance tripping on start-up. The magnetic trip threshold is fixed at 8 x In ±20 %, so it clears a short-circuit at roughly 160 A or above, while the thermal-magnetic element protects the cable against sustained overload. Breaking capacity is the headline selector: 10 kA Icu at 220…240 V AC (EN/IEC 60947-2) and 6 kA Icn at 230 V AC (EN/IEC 60898-1). That dual rating means the part qualifies for industrial panel coordination (60947-2) and residential/commercial final-circuit duty (60898-1). At 12…60 V DC it holds 15 kA Icu, so it also works in DC sub-distribution for control power supplies or battery-backed loads.
It carries dual certification to EN/IEC 60947-2 and EN/IEC 60898-1, plus tropicalisation per EN/IEC 60068-2-78 (95 % RH, 55 °C). That means it is accepted in both industrial control panels and final-distribution boards across most jurisdictions. The isolation marking (suitability for isolation: yes per both standards) confirms it can be used as a disconnecting means where local code requires it.
The toggle actuator and trip-indicator window give local status without opening the panel door. Overvoltage category IV suits it for the main distribution board, not just sub-circuits.
