The Schneider Electric A9D52606 is an Acti9 iDPN Vigi RCBO — a combined overcurrent and earth-leakage protection device in a single 36 mm wide module, 1P+N poles, rated 6 A with a C-curve magnetic trip (5...10 x In) and 100 mA residual current sensitivity.
The 6 A rated current (In) and C-curve mean the thermal-magnetic trip holds steady up to 6 A continuous load and trips magnetically between 30 A and 60 A for short-circuit or high-inrush events — typical for lighting or general-purpose socket circuits where inrush isn't extreme. The 100 mA earth-leakage sensitivity is less sensitive than a 30 mA unit; it's suited for circuits where nuisance tripping from leakage in long cable runs or equipment with natural leakage (like heaters or older motors) would be a problem, while still providing personnel protection in some industrial settings.
Neutral on the left, phase on the right — standard for the iDPN Vigi range.
