The Schneider Electric A9D99616 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — a single-module device combining a 16 A thermal-magnetic MCB and a 30 mA earth-leakage trip in one 1P+N unit. The 16 A rated current (In) and C-curve magnetic trip (5–10 × In) mean it handles general-purpose lighting and socket circuits where inrush from small motors or fluorescent ballasts stays under 160 A peak before the magnetic coil clears it. The 30 mA sensitivity covers personnel protection (indirect contact and additional fire protection per IEC 60364). Breaking capacity is 6000 A Icn at 220–240 V AC 50 Hz, certified to EN/IEC 61009-2-1 — adequate for most residential and light commercial distribution boards where the prospective short-circuit current at the outgoer does not exceed 6 kA. The limitation class 3 rating means it restricts let-through energy under fault conditions, reducing stress on downstream wiring.
Clip-on mounting to DIN rail (EN 60715), 36 mm width (4 × 9 mm pitches). Terminals accept 1–16 mm² rigid or 1–10 mm² flexible (with or without ferrule); strip length 15 mm, torque 2 N·m.
Environmental and compliance details
Rated for pollution degree 3 (industrial or damp environments), overvoltage category III (distribution board level), and tropicalisation class 2 per IEC 60068-1 (handles 95 % RH at 55 °C). Mechanical and electrical durability are both rated at 20 000 cycles — the toggle switch and internal mechanism are matched for that service life.
