The Schneider Electric A9DC7716 is an Acti9 iCV40 residual current circuit breaker with overcurrent protection (RCBO) — a 3P+N unit rated 16 A, C-curve, with 6 kA breaking capacity at 400 V AC and integrated 300 mA earth-leakage protection.
The 16 A rated current (In) with C-curve (magnetic trip 5–10× In) suits general-purpose loads like lighting, socket outlets, and small appliances where inrush is moderate — not for motor starting or high-inductive loads that would need a D-curve. The 300 mA earth-leakage sensitivity provides personal protection against indirect contact (fire protection level) but is not rated for life-safety (30 mA) — use where the circuit feeds fixed equipment, not hand-held tools.
Clip-on DIN-rail mount, 10 modular pitches (90 mm wide). Tunnel terminals accept 1–16 mm² rigid or 1–10 mm² flexible; tighten to 2 N·m. Pollution degree 3 (conductive or dry non-conductive pollution) is typical for industrial panels.
