The integrated earth-leakage element trips at 10 mA sensitivity, making it suitable for circuits requiring both overcurrent and high-sensitivity ground-fault protection in a compact DIN-rail footprint. The thermal-magnetic trip unit handles overloads; the electronic earth-leakage section handles ground faults down to 10 mA. Snap it onto DIN rail, 2 module pitches wide (18 mm per pitch), with tunnel terminals accepting up to 16 mm² rigid upstream and 10 mm² downstream. The 10 mA earth-leakage sensitivity is the standout spec here — most general-purpose RCBOs are 30 mA. A 10 mA trip threshold means it will clear ground faults before they reach the let-go threshold for human contact, which is why you see this sensitivity specified for socket circuits in wet areas, laboratories, or medical locations where additional shock protection is required. If your fault current at the board exceeds 6 kA, you need to coordinate upstream with a higher-rated MCB or fuse. Limitation class 3 means the RCBO limits let-through I²t enough to protect downstream wiring under short-circuit conditions. ## Installation notes from the panel Mounts on DIN rail via the clip-on mechanism. Neutral is on the left, which is the standard Acti9 orientation. Tunnel terminals: upstream accepts 1–16 mm² rigid or flexible, downstream 1–10 mm². Wire stripping length is 13 mm upstream, 11 mm downstream. The toggle gives ON/OFF indication and the contact position indicator confirms the state of the main contacts. Locking facilities allow padlocking in the OFF position for isolation during maintenance.","metaTitle":"Schneider Electric A9D40620 Acti9 RCBO, 20 A, 10 mA, C-Curve","metaDescription":"Schneider Electric A9D40620 Acti9 ISPN Vigi RCBO. 20 A rated, 10 mA earth leakage, C-curve, 6 kA breaking capacity.
