The Schneider Electric A9N2P16DIN is an Acti9 xC60 miniature circuit breaker rated at 16 A with a D tripping curve, meaning its magnetic trip threshold sits at 12 x In ±20 % — designed for loads with high inrush, like motor circuits or transformers, where the start-up surge would nuisance-trip a B or C curve. Breaking capacity is 10 kA Icn at 380–415 V AC 50/60 Hz per IS/IEC 60947-2, with a 6 kA Icu at 100–125 V DC for DC circuits. The 2-pole unit clips onto a 35 mm DIN rail, occupies 4 x 9 mm pitches (36 mm wide), and stands 85 mm tall with a 77.5 mm depth — fits standard distribution boards with room for gland plates and wiring ducts.
Integration notes
Clip-on mounting on 35 mm DIN rail — no screws needed, snaps into place and releases with a screwdriver slot.
