The Schneider Electric A9N1P20CGN is a 1-pole Acti9 xC60 miniature circuit breaker rated 20 A with a C-curve trip characteristic. It clips onto a 35 mm DIN rail and protects a single phase of a 220–240 V AC 50/60 Hz distribution circuit.
Breaking capacity and standard compliance
Rated breaking capacity is 10,000 A Icn at 240 V AC, certified to IS/IEC 60898-1. The limitation class is 3 per IS/IEC 60898-1, meaning it limits let-through energy enough to coordinate with downstream equipment in a well-designed panel.
Depth is 77.5 mm, height 85 mm — fits most enclosures with a 100 mm+ internal depth.
