The Schneider Electric A9N3P10BIN is a 3-pole miniature circuit-breaker from the Acti9 xC60 range, rated 10 A with a B-curve thermal-magnetic trip unit. The 10 kA breaking capacity at 380–415 V AC (IS/IEC 60947-2) means it can safely interrupt a fault current up to that level without welding its contacts or cascading damage upstream — essential for protecting downstream wiring and loads in a distribution panel.
Clip-on mounting to a standard 35 mm DIN rail, occupying 6 x 9 mm pitches (54 mm width). The IP20 finger-safe enclosure suits clean, dry indoor panels — typical for commercial or light industrial distribution boards. Tunnel-type terminals accept up to 25 mm² rigid or 16 mm² flexible cable; wire strip length is 13 mm for top or bottom connection. Earth-leakage protection requires a separate block (not integrated).
