The Schneider Electric A9F68201 is a 1 A, 2-pole miniature circuit-breaker from the Acti9 iT60N range, built for distribution boards where a C-curve trip characteristic is needed to handle moderate inrush from small motor or lighting loads. The C-curve means magnetic tripping occurs at 8 x In (±20 %) — so at 1 A rated current, the instantaneous trip threshold sits around 8 A, which keeps it from nuisance-tripping on capacitor or transformer inrush while still clearing a hard fault fast. Breaking capacity is the headline here: 50 kA Icu at 415 V AC (per EN/IEC 60947-2) and 10 kA Icn at 400 V AC (per EN/IEC 60898-1). The 10 kA Icn rating under 60898-1 is the standard domestic/commercial service capacity; the 50 kA Icu under 60947-2 is the industrial ultimate capacity, giving you SCCR headroom for coordination studies.
Integration and compliance details
DIN-rail mount, 36 mm wide, with a removable comb busbar installed for easy phase linking. Terminals accept 1…25 mm² rigid or 1…16 mm² flexible wire; strip length 14 mm, torque to 2 N·m. IP20 finger-safe (B type per IEC 60529). Pollution degree 3, overvoltage category IV — suitable for main distribution panels, not just sub-distribution. Ambient operating range -35…70 °C, storage -40…85 °C, with tropicalisation level 2 (conforming to EN/IEC 60068-2-78 for 95 % RH). Isolation capability is confirmed per both 60898-1 and 60947-2, with a visible contact position indicator and a trip indicator for quick fault identification.
