Product details

It is rated 25 A with 30 mA sensitivity, Type A-SI (Super Immunised), meaning it handles sinusoidal AC and pulsed DC fault currents while resisting nuisance tripping from high-frequency harmonics or transient surges common on modern electronic loads.

Mounts via clip-on to DIN rail (35 mm) and connects to the load side of a 1P+N MCB using the supplied screw terminals. The 36 mm width occupies two 9 mm pitches, leaving space for adjacent modules in a consumer unit or distribution board. Pollution degree 3 per EN/IEC 61009-2-1 suits standard industrial and commercial panel environments where some conductive pollution is expected.

Earth-leakage protection class

Type A-SI (Super Immunised) means this RCD is voltage-independent — it trips on residual current without needing an external supply — and is immune to unwanted tripping from 50 Hz harmonics, switching transients, and up to 3 kHz waveforms. This makes it a direct fit for circuits feeding variable-speed drives, LED drivers, UPS equipment, or other loads that generate high-frequency leakage. The instantaneous time delay means no intentional delay before tripping on a fault.

Frequently asked questions

What is the closest alternative to A9Y74625 in the Acti9 family?

The closest sibling is the standard Acti9 Vigi iCG40 with the same 25 A, 30 mA rating but in Type A (non-SI) — the A9Y74625 is the Type A-SI variant with super-immunised characteristics for harmonic-rich loads. If your circuit has no electronic loads or drives, the Type A version may be a lower-cost fit, but for VFD, UPS, or LED circuits the A-SI is the correct choice.

How do I get current pricing and availability for A9Y74625?

Submit an RFQ through this listing. Pricing and availability are confirmed at quote time against a purchase order — no stock count or price is published here, but the part is sourced to order through independent distribution channels.

What compliance documentation does Schneider provide for A9Y74625?

The device carries IMQ quality label and is certified to EN/IEC 61009-2-1. It is designed for AC networks at 50/60 Hz. For RoHS, REACH, and specific UL/IEC declarations, refer to the manufacturer's compliance documentation available on the Schneider Electric portal.
