25 A D-curve MCB for distribution boards
The Schneider Electric A9N1P25DIN is a 1-pole miniature circuit breaker from the Acti9 xC60 range, rated 25 A with a D-curve magnetic trip characteristic. The D-curve trips magnetically at 12 x In ±20 % — meaning instantaneous trip between 240 A and 360 A — which suits loads with high inrush current such as small motors, transformers, or solenoid banks where a B- or C-curve would nuisance-trip on startup. Breaking capacity is 10 kA Icu at 220…240 V AC 50/60 Hz per IS/IEC 60947-2, and 15 kA Icu at 12…48 V DC, so it clears fault currents up to those levels without cascading upstream. The thermal-magnetic trip unit covers overload and short-circuit protection on a single pole.
Depth is 77.5 mm, height 85 mm — fits standard distribution board enclosures with a 35 mm rail and adequate front clearance for the toggle actuator. IP20 finger-safe protection on the front face; pollution degree 3 per the standard.
