The Schneider Electric A9Q22325 is an Acti9 Vigi iC60 add-on residual current device (RCD) — a 3-pole, 25 A, 100 mA, Type A earth-leakage block that clips onto the downstream side of an iC60 MCB. It is voltage-independent, meaning the trip mechanism does not rely on an external supply to detect leakage; the fault current itself powers the solenoid. Rated for 400 V AC 50/60 Hz networks, it meets IEC 61009-1 and EN 61009-1. The 100 mA sensitivity and Type A waveform coverage (sinusoidal AC plus pulsed DC up to 6 mA) suit it for general-purpose outgoer protection in commercial and light industrial final circuits.
Mounts via clip-on onto DIN rail, occupying 6 x 9 mm pitches (54 mm width). The bottom tunnel terminals accept 1…25 mm² rigid or 1…16 mm² flexible conductors, stripped to 14 mm, tightened to 2 N·m. The plug-in electrical connection to the adjacent iC60 MCB means no additional wiring between the two — the block mates directly. IP20 on the body, IP40 inside a modular enclosure. Ambient operating range -25…60 °C; storage -40…85 °C.
