The Schneider Electric A9F68263 is an Acti9 iT60N miniature circuit breaker rated at 63 A with a C-curve trip characteristic, 2 poles, and a 36 mm DIN-rail footprint. Breaking capacity reaches 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V AC, and 10 kA at 380–415 V AC per EN/IEC 60947-2; under EN/IEC 60898-1 it delivers 10 kA Icn at 400 V AC. That dual rating means the same unit satisfies both industrial (60947-2) and residential/commercial (60898-1) installations, simplifying BOM consolidation.
Integration and wiring constraints
Mounts on DIN rail with a removable comb busbar installed. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible wire; strip length is 14 mm. IP20 B finger-safe terminals per IEC 60529. Tropicalisation class 2 per EN/IEC 60068-2-78 handles 95% relative humidity.
Dual certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (residential/commercial). Suitability for isolation confirmed under both standards. Local trip indicator and contact position indicator are standard.
