The Schneider Electric A9N4P63BGN is a 4-pole miniature circuit breaker from the Acti9 xC60 series, rated at 63 A with a B-curve magnetic trip characteristic (3 to 5 times In). It's a thermal-magnetic breaker built for distribution duty in 35 mm DIN-rail panels, clip-on mount, with a 10 kA breaking capacity at both 240 V and 415 V AC per IS/IEC 60898-1.
The 63 A rated current (In) is the continuous load this breaker can carry without tripping under normal conditions — sized for a main feeder or a heavy sub-feed in a distribution board.
Clip-on mount onto 35 mm DIN rail — standard for any panel builder. The 4-pole (4P) body takes up 8 x 9 mm pitches (72 mm width), so plan your DIN-rail fill accordingly.
