The Schneider Electric A9N1P06DIN is a 1-pole miniature circuit-breaker from the Acti9 xC60 range, rated 6 A with a D tripping curve. The D curve means magnetic trip occurs at 12 x In (72 A) with a +/-20 % tolerance, sized for loads with high inrush such as small motor starters or transformer primaries.
Breaking capacity is 10 kA Icu at 220…240 V AC 50/60 Hz, 15 kA Icu at 12…48 V DC, and 6 kA Icu at 60 V DC, all per IS/IEC 60947-2. The limitation class is 3 per IS/IEC 60947-2, meaning it limits let-through energy enough to protect downstream wiring in a coordinated distribution scheme. Suitability for isolation is confirmed to the same standard — the toggle provides an air gap you can lock out.
Clip-on mounting to 35 mm DIN rail, 18 mm wide, 85 mm tall, 77.5 mm deep — fits a standard distribution board without overhang.
