The Schneider Electric A9N4P16DIN is an Acti9 xC60 miniature circuit breaker rated 16 A with a D tripping curve, 4 poles, and a breaking capacity of 10 kA Icn at 380–415 V AC 50/60 Hz per IS/IEC 60947-2. At 220–250 V DC it breaks 6 kA Icu. The D curve means magnetic trip occurs at 12 x In (±20 %), so it handles high inrush loads like motor starters and transformers without nuisance tripping. IP20 finger-safe terminals suit enclosed distribution boards.
Suitability for isolation is confirmed per the same standard.
