The 4-module (9 mm pitch each) body mounts on DIN rail via the clip-on mechanism, so it integrates into a standard distribution board or sub-panel as a combined RCBO assembly when paired with the matching MCB. The 40 A rated current (In) sets the continuous load the RCD can carry without derating; it matches a 40 A MCB in the same Acti9 range, so the pair forms a coordinated RCBO. The instantaneous time delay (no intentional delay) ensures the RCD clears the fault within the standard 40 ms window, which is critical for coordination with upstream selective RCDs — the instantaneous unit trips first, leaving the upstream time-delayed device to act as backup. Clip-on mounting on DIN rail — no tools needed for the rail attachment. The neutral position is left, so verify the orientation matches the busbar and the adjacent MCB's neutral take-off point. Bottom tunnel terminals accept 1…16 mm² rigid or 1…10 mm² flexible cable; tighten to 2 N·m. Strip length is 14 mm for the bottom connection. The electrical connection to the MCB is by screws, so the RCD is mechanically and electrically linked to the line-side breaker. IP20 on the body (finger-safe), IP40 inside a modular enclosure — standard for distribution boards.","metaTitle":"A9Y84740 Acti9 Vigi iC40 40A 30mA RCD, 3P+N","metaDescription":"Schneider Electric A9Y84740 Acti9 Vigi iC40 add-on RCD, 40 A rated, 30 mA sensitivity, Type A-SI, 400 V AC, DIN rail, current production.

The A9Y84740 is a 3P+N, 40 A, 30 mA, Type A-SI unit. A sibling with a lower current rating (e.g., 25 A) or a different pole configuration (e.g., 2P) would be a different order code — the mechanical footprint and wiring pattern are the same, but the thermal rating and the neutral arrangement differ. For a direct replacement, match the In, poles, sensitivity, and Type exactly."},{"question":"Where can I buy the A9Y84740 and how is it quoted?","answer":"This part is sourced through independent distribution channels. It is quoted to order against an RFQ — availability and current pricing are confirmed at the time of the quote. Submit an RFQ for a firm price and lead time."},{"question":"What compliance documentation does Schneider provide for the A9Y84740?","answer":"The A9Y84740 carries IMQ and OVE quality labels, and is designed to EN/IEC 61009-2-1 (RCD standard). The manufacturer typically provides a Declaration of Performance (DoP) and CE marking documentation. For specific RoHS/REACH/UL declarations, request them with the RFQ — they are available from the manufacturer's documentation portal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/A9Y84740","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/A9Y84740 when reusing this data.
