D-curve 63 A MCB for motor and transformer branch circuits
The Schneider Electric A9N1P63DGN is a 1-pole miniature circuit breaker from the Acti9 xC60 range, rated 63 A continuous current with a D tripping curve that triggers magnetically at 10 to 14 times In. Breaking capacity is 10 kA Icn at 240 V AC 50/60 Hz, certified to IS/IEC 60898-1 — enough for most distribution sub-panels in industrial and commercial buildings.
Panel integration and environment
The 1P unit occupies 2 x 9 mm pitches. Tropicalisation treatment per IEC 60068-1 (class 2) adds corrosion resistance for humid environments — relevant for mill or coastal plant rooms.
