The Schneider Electric A9N3P50CIN is a 3-pole Acti9 xC60 miniature circuit-breaker rated 50 A with a C curve magnetic trip — 8 x In ±20 % — meaning it holds through moderate inrush and trips on short-circuit fast enough to protect downstream cable. Breaking capacity is 10 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. Clip-on mounting to 35 mm DIN rail, 54 mm wide, 85 mm tall, 77.5 mm deep — fits a standard 6-module pitch on the rail.
Construction and environment
IP20 finger-safe terminals, pollution degree 3 (conductive pollution expected), overvoltage category IV — suitable for main distribution panels where the breaker sees the utility-side surge. Mechanical durability 20 000 cycles, electrical 10 000 cycles at rated load.
The A9N3P50CIN carries a current lifecycle stage.
