Acti9 xC60 40 A MCB, C-Curve, 4-Pole
The Schneider Electric A9N4P40CGN is an Acti9 xC60 miniature circuit breaker rated 40 A with a C-curve magnetic trip characteristic (5...10 x In), 4 protected poles, and a 10 kA breaking capacity at 240 V AC and 415 V AC per IS/IEC 60898-1. Rated operational voltage spans 220...240 V AC and 380...415 V AC at 50/60 Hz, making it suitable for standard single-phase and three-phase distribution panels in commercial and light industrial installations.
Clip-on mounting onto a 35 mm DIN rail occupies 72 mm width (8 x 9 mm pitches) and 77.5 mm depth, fitting standard distribution board spacing. Terminals accept up to 35 mm² rigid or 25 mm² flexible conductors via tunnel-type biconnect terminals on the bottom; wire stripping length is 13 mm, tightening torque 3.5 N·m.
Designed and tested to IS/IEC 60898-1 for miniature circuit breakers, with tropicalisation level 2 per IEC 60068-1 for damp-heat resistance (95 % RH at 55 °C). Overvoltage category IV (suitable for main incoming supply points), limitation class 3 (energy limiting) per IS/IEC 60898-1, and rated for 10,000 electrical cycles / 20,000 mechanical cycles.
