The A9Q30225 is a 2-pole add-on residual current device (RCD) block from the Acti9 Vigi iC60 series, designed to clip onto the side of an Acti9 iC60 MCB. It provides earth-leakage protection at 10 mA sensitivity with Type A-SI (Super Immunised) characteristic, meaning it handles pulsed DC fault currents and resists nuisance tripping from high-frequency inverter leakage — useful on lines feeding electronics or VFDs. Rated operational voltage is 230...240 V AC 50/60 Hz per IEC 61009-1, with a rated insulation voltage of 500 V AC and impulse withstand of 6 kV. The block occupies 3 DIN pitches (27 mm wide) and clips onto the rail — standard panel integration for a distribution board or sub-panel outgoer.
Lifecycle status — sourcing reality
Schneider lists the A9Q30225 as Obsolete. For a BOM line frozen on this exact code, the only channel is surplus / aftermarket sourcing — quoted against an RFQ, with availability and pricing confirmed at time of quote.
Integration and fit notes
Clip-on mounting to DIN rail; mates electrically via plug-in connection to the iC60 MCB. IP20 on the body, IP40 inside a modular enclosure. Depth of 73.5 mm (91 mm height) means it protrudes further than a standalone MCB — verify gland-plate clearance if the enclosure is tight. Pollution degree 3 per IEC 60947-2.
