The Schneider Electric A9N2P03CGN is an Acti9 xC60 miniature circuit breaker — a 3 A, C-curve, 2-pole unit rated for 10 kA breaking capacity at 240 V AC and 415 V AC per IS/IEC 60898-1. Thermal-magnetic trip, toggle control, clip-on mount to 35 mm DIN rail.
Snaps onto a 35 mm DIN rail in the distribution board — 36 mm width (4 x 9 mm pitches), 85 mm height, 77.5 mm depth. Tightening torque 2 N·m. IP20 finger-safe front, pollution degree 3, overvoltage category IV — standard for main distribution panels.
C-curve magnetic trip threshold is 5 to 10 times In (15 to 30 A), so it's sized for inductive loads like small motors or lighting banks where inrush is moderate. Rated for 20,000 electrical and 20,000 mechanical cycles. Earth-leakage protection requires a separate block — this is the MCB only.
