The Schneider Electric A9Q26325 is an Acti9 Vigi iC60 add-on residual current device — a 3-pole, 25 A, 500 mA Type A earth-leakage block that clips onto the outgoing side of a compatible iC60 MCB. It is a voltage-independent, instantaneous-trip unit, meaning it does not need a separate power supply to detect leakage and clears the fault as soon as the residual current exceeds 500 mA. That makes it a straight swap-in for existing iC60 installations where you need to add ground-fault protection without re-running the feeder.
Clip-on mounting onto a DIN rail, 6 modules wide (54 mm). The bottom terminals accept rigid cable up to 25 mm² or flexible with ferrule up to 16 mm², and the strip length is 14 mm.
