Product details

The Schneider Electric A9Q16425 is an Acti9 Vigi iC60 add-on residual current device — 4 poles, 25 A rated current, 500 mA earth-leakage sensitivity, Type AC, instantaneous trip, rated for 230…415 V AC 50/60 Hz networks. It clips onto the outgoing side of an iC60 MCB via the plug-in electrical connection, turning a standard breaker into a combined MCB/RCD unit without extra wiring or panel space.

Mounts on DIN rail via the clip-on mechanism — no tools needed for installation or removal. Occupies 6 x 9 mm pitches, so 54 mm width on the rail. The tunnel-type terminals on the bottom accept 1…25 mm² rigid or 1…16 mm² flexible conductors, stripped to 14 mm, tightened to 2 N·m. Bottom comb-busbar compatible. IP20 on the body, IP40 inside a modular enclosure.

Rated insulation voltage 500 V AC, impulse withstand 6 kV. Pollution degree 3 per IEC 60947-2 — suitable for industrial panels where conductive deposits may occur. The residual current trip is voltage-independent, so it operates even if the line voltage drops or is lost — a key reliability point for safety circuits.

Frequently asked questions

What is the closest pin-compatible alternative to A9Q16425 in this component family?

Within the Acti9 Vigi iC60 family, the closest alternative would be a variant with a different sensitivity or poles count — for example, a 2P or 300 mA version. All share the same plug-in mechanical interface and DIN-rail footprint, so swapping requires only verifying the new rating against the circuit's earth-leakage and current requirements.

What compliance documentation does Schneider Electric provide for A9Q16425?

The A9Q16425 is designed and certified to EN/IEC 61009-1 and EN/IEC 61009-2-1. It carries the CE mark, and Schneider Electric provides a declaration of conformity covering these standards. RoHS and REACH compliance documentation is available on request.

Where can I buy A9Q16425 and what is the lead time?

The A9Q16425 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time; submit an RFQ for a firm lead-time estimate.
