The Schneider Electric A9D54610 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — a single-module, 1P+N unit rated at 10 A with a B tripping curve and integrated 30 mA earth-leakage protection.
The 30 mA sensitivity is the standard for personal protection against indirect contact in dry indoor environments (IP20 rated, IP40 in a modular enclosure). Breaking capacity of 4500 A Icn at 230...240 V AC 50 Hz conforms to EN/IEC 61009-2-1, which is adequate for most domestic and small commercial sub-distribution boards where the prospective short-circuit current stays under that level. The limitation class 3 rating means it limits let-through energy well, which helps with downstream cable protection and coordination.
Neutral is on the left. Terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible (with or without ferrule); strip length 15 mm, tighten to 2 N.m. The toggle provides local ON/OFF and fault-trip indication.
