The Schneider Electric A9D69606 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one module wide, combining a 6 A B-curve MCB and a 300 mA earth-leakage trip in a single 1P+N unit. Breaking capacity is 6000 A Icn at 230–240 V AC, 50 Hz, per EN/IEC 61009-2-1 — adequate for residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold.
Clip-on mounting to DIN rail (EN 60715), 36 mm wide (4 × 9 mm pitches), 85 mm tall, 73 mm deep — occupies one modular slot in a standard distribution board. Terminals accept 1–16 mm² rigid or 1–10 mm² flexible; wire strip length 15 mm, tightening torque 2 N·m. Neutral is on the left, phase on the right — wire it in that order to keep the internal arc chamber aligned.
