The Schneider Electric A9N1P10DGN is a miniature circuit breaker from the Acti9 xC60 family, configured as a single-pole unit rated at 10 A with a D tripping curve and a 10 kA interrupting capacity verified to IEC 60898-1.
As a 1-pole DIN-rail mount MCB, the A9N1P10DGN occupies one module width (roughly 18 mm) in a standard distribution board or sub-panel enclosure. The Acti9 xC60 series shares a uniform footprint and busbar pitch, so it integrates alongside other xC60 breakers, RCDs, and accessories without adapters. The D curve is worth noting for panel builders: if the downstream load is a resistive heater or general-purpose socket circuit, a C or B curve would be a better fit — D is specifically for high-inrush inductive loads where the starting surge exceeds 10× rated current.
