Product details

The A9Y81340 is a Schneider Electric Acti9 Vigi iC40 add-on residual current device (RCD) — a voltage-independent, instantaneous-trip module that clips onto a compatible Acti9 MCB to provide earth-leakage protection on a 3P outgoing circuit. Rated at 40 A, 300 mA sensitivity, Type A (pulsating DC and sinusoidal AC leakage), it mounts on DIN rail via clip-on and occupies 4 x 9 mm pitches (90 mm wide).

The 300 mA sensitivity covers general earth-leakage protection on outgoing circuits. Voltage-independent tripping means the RCD operates without needing a separate power supply — the leakage current itself provides the energy to trip the mechanism. This makes it a reliable retrofit onto an existing Acti9 MCB (screw-connected via the busbar comb or direct wiring). IP20 on the body, IP40 in a modular enclosure — keep it inside the cabinet.

Frequently asked questions

What is the closest pin-compatible alternative to A9Y81340 in this component family?

Within the Acti9 Vigi iC40 range, the only difference between order codes is the pole count, rated current, and sensitivity — the A9Y81340 is the 3P, 40 A, 300 mA, Type A variant. For a different sensitivity or current rating, look at other Vigi iC40 part numbers; the mechanical footprint (4 x 9 mm pitches, clip-on DIN rail) is shared across the family.

What is A9Y81340's listed depth (74 mm) on this component line?

The depth is 74 mm, which matches the standard Acti9 Vigi iC40 module depth — it protrudes that far from the DIN rail, so check clearance in shallow enclosures.

What is A9Y81340's listed range (Acti9) on this component line?

The range is Acti9, Schneider's modular DIN-rail system for final distribution — the Vigi iC40 is the add-on RCD series within that range.
