The Schneider Electric A9N3P63DIN is a 3-pole miniature circuit-breaker from the Acti9 xC60 range, rated at 63 A with a D tripping curve.
Breaking capacity is 6 kA Icn at 380–415 V AC (50/60 Hz) and 15 kA Icu at 100–125 V DC, both per IS/IEC 60947-2. The thermal-magnetic trip unit covers overloads (thermal bimetal) and short-circuits (magnetic coil). Limitation class 3 per IS/IEC 60947-2 means it limits let-through energy enough to protect downstream equipment in a fault — a useful detail for coordination studies.
Strip length is 13 mm for top or bottom connection. Biconnect bottom terminals allow daisy-chaining without extra links.
