The Schneider Electric A9V07263 is a Vigi iC60 add-on residual current device from the Acti9 range. It clips onto the side of an iC60 MCB to add earth-leakage protection — 2 poles, rated 63 A continuous, with 30 mA sensitivity and Type A detection for pulsating DC fault currents. The unit is voltage-independent, meaning it trips on leakage alone without needing a separate power supply to the electronics.
Mounts via clip-on onto DIN rail, side-by-side with the companion iC60 MCB. The assembly takes 4 module pitches (9 mm each) — 72 mm total width. IP20 on the device body, IP40 inside a modular enclosure. Rated insulation voltage 500 V AC, operational voltage 400…415 V AC at 50/60 Hz, impulse withstand 6 kV per EN/IEC 61009-1. Pollution degree 3 — suitable for industrial panels where conductive contamination is controlled but not excluded.
The 30 mA sensitivity catches leakage currents that could be lethal through a grounded person — standard for socket-outlet and final-circuit protection in many jurisdictions. Type A detection covers sinusoidal AC faults plus pulsating DC, which is what most single-phase electronics and switched-mode power supplies generate. Instantaneous trip means no intentional time delay; it clears the fault within the standard response time of the RCD mechanism. Ambient operating range -25…60 °C, storage -40…85 °C.
