The A9N4P10CGN is a Schneider Electric Acti9 xC60 miniature circuit breaker — a 4-pole, 10 A thermal-magnetic MCB with a C-curve trip characteristic.
Rated Icn of 10,000 A at both 240 V and 415 V AC (50/60 Hz) per IS/IEC 60898-1. That 10 kA symmetrical rating holds across the full voltage range, which simplifies coordination — you don't need a different breaker for the higher-voltage leg in a 415 V three-phase panel. The limitation class 3 rating means it lets through less energy during a fault than a class 1 or 2 device, so downstream cable and busbar can be sized closer to the load current rather than the full prospective fault current.
The 4-pole body takes 8 x 9 mm pitches of DIN space (72 mm wide), so plan for that footprint in the distribution board. IP20 finger-safe terminals only — no washdown rating; keep it inside the enclosure.
