The Schneider Electric A9N1P20BIN is an Acti9 xC60 miniature circuit breaker — a 1-pole, 20 A rated unit with a B-curve trip characteristic, designed for distribution duty in 35 mm DIN-rail panels. It carries a 10 kA Icu at 220–240 V AC (IS/IEC 60947-2) and 15 kA at 12–48 V DC, so it handles standard residential and light commercial fault levels without cascading upstream. The thermal-magnetic trip unit gives you a magnetic tripping limit of 4 x In ±20 %, meaning it clears short-circuit faults fast while letting motor inrush ride through.
Standards & approvals
Rated for isolation per IS/IEC 60947-2, overvoltage category IV, and tropicalisation class 2 per IEC 60068-1 (95 % RH at 55 °C). Limitation class 3 keeps let-through energy low for downstream equipment protection. Separate earth-leakage block can be added if needed.
