The Schneider Electric A9N3P10CGN is an Acti9 xC60 miniature circuit-breaker — a 3-pole, 10 A thermal-magnetic MCB with a C-curve (magnetic trip at 5 to 10 x In). The 10 kA Icn at 240 V AC and 10 kA at 415 V AC (both per IS/IEC 60898-1) give it enough interrupting capacity for most branch-circuit faults without cascading upstream.
The 10 A rated current (In) is the continuous load the breaker carries without tripping. That makes it a general-purpose branch-circuit breaker, not a motor-circuit protector (which would use a D-curve). Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, 50/60 Hz, per IS/IEC 60898-1. The standard itself (IS/IEC 60898-1) certifies it for overcurrent protection in household and similar installations. Rated operational voltage is 220…240 V AC or 380…415 V AC, 50/60 Hz. The 3-pole version (3P) switches all three phases simultaneously, so it fits a three-phase distribution board. The toggle gives local ON/OFF indication.
Width is 54 mm (6 x 9 mm pitches), height 85 mm, depth 77.5 mm. Wire stripping length is 13 mm for top or bottom connection. The biconnect feature allows two conductors per terminal on the bottom side. IP20 protection means it is finger-safe but not sealed against moisture — install inside a panel with a higher-rated enclosure if washdown is present. Earth-leakage protection is handled by a separate block (not integrated), so you add an RCCB upstream or downstream as needed.
