Acti9 iC60N — 20 A, 3P+N, C-Curve MCB
The Schneider Electric A9F04720 is a 20 A, 3P+N miniature circuit breaker from the Acti9 iC60N series, with a C-curve trip characteristic. Rated for both AC and DC networks at 50/60 Hz, this MCB carries a breaking capacity of 36 kA Icu at 12-133 V AC, 20 kA Icu at 220-240 V AC, 10 kA Icu at 380-415 V AC, and 6 kA Icu at 440 V AC, per EN/IEC 60947-2. The Icn rating per EN/IEC 60898-1 is 6000 A at 400 V AC. The C-curve means magnetic tripping occurs at 8 x In ±20%, suitable for circuits with moderate inrush currents like lighting or small motor loads. The 3P+N configuration protects three phases with a switched neutral on the left side. Overvoltage category IV and pollution degree 3 ratings confirm it is suitable for main distribution panels in industrial environments. The IP20 finger-safe enclosure is standard for panel-mount breakers; no washdown rating.
Panel Integration
Occupies 8 x 9 mm pitches (72 mm) on the DIN rail. The 78.5 mm depth leaves clearance for standard enclosure depths. Double terminals top and bottom accept 1-25 mm² rigid or 1-16 mm² flexible conductors.
