The Schneider Electric A9N1P63CGN is an Acti9 xC60 miniature circuit breaker — a 1-pole, 63 A thermal-magnetic MCB with a C-curve trip characteristic, built to IS/IEC 60898-1 for distribution in residential and light commercial panels. The 63 A rating means it protects a branch circuit carrying up to that continuous current; the C-curve (magnetic trip between 5 and 10 times In) is the standard choice for inductive loads like small motors, pumps, and lighting ballasts where inrush is moderate.
Clip-on mounting to a standard 35 mm DIN rail, occupying 18 mm width — two 9 mm pitches. That's a single module slot in a consumer unit or distribution board. Tightening torque is 3.5 N.m, and wire strip length is 13 mm for top or bottom connection. IP20 finger-safe front is standard for enclosed panels; no washdown rating here, so keep it behind a panel door.
