What this RCBO does and why it matters for your panel
The Schneider Electric A9DG2606 is an Acti9 iCV40 RCBO — a combined overcurrent and earth-leakage protection device in a 1P+N format, rated 6 A with a B-curve trip characteristic and 30 mA residual-current sensitivity.
Breaking capacity is 4500 A Icn at 230 V AC, 50/60 Hz, per EN/IEC 61009-2-1. The limitation class is 3, meaning it limits let-through energy under fault conditions, reducing stress on downstream wiring and equipment. The thermal-magnetic trip unit combines a bimetal strip for overload protection (time-delayed, inversely proportional to current) and a solenoid for short-circuit protection (instantaneous above the magnetic threshold). The magnetic tripping limit of 3–5 x In means for a 6 A device, it trips instantaneously between 18 A and 30 A — typical for B-curve coordination with cable protection. Integrated earth-leakage protection at 30 mA sensitivity covers both sinusoidal AC residual currents (Type AC, implied by the AC network designation) and meets the standard requirement for socket-outlet circuits in many IEC-based wiring regulations.
Mounting and wiring — what fits where
Clip-on mounting to a 35 mm DIN rail, with tunnel-type terminals accepting 1–16 mm² rigid or 1–10 mm² flexible conductors. The 9 mm connection pitch between phase and neutral matches standard Acti9 busbar systems, so it integrates directly into a Schneider distribution board without adaptors.
