Earth-leakage sensitivity is 300 mA, instantaneous trip. Voltage-independent tripping means the RCD operates without needing a separate power supply — the fault energy itself drives the mechanism. That makes it reliable even if the neutral is lost upstream, a common concern in older installations or temporary supply scenarios. Insulation voltage is 500 V AC. Impulse withstand is 6 kV. The block is 117 mm wide (7 x 9 mm pitches), 95 mm tall, 73 mm deep, and IP20 rated for finger-safe installation inside an enclosure. Tunnel-type terminals accept 1...50 mm² rigid or 1...35 mm² flexible conductors; tighten to 3.5 N·m. Wire stripping length is 15 mm. Electrical connection to the upstream MCB is by screws — this is a mechanical and electrical add-on, not a standalone device. It occupies the outgoer group or incomer position in the panel. Designed to EN 61009 and IEC/EN 61009-2-1, with pollution degree 3 per IEC 60947-2.","metaTitle":"Schneider Electric A9N18573 Acti9 Vigi C120, 2P, 300 mA, Typ","metaDescription":"Schneider Electric A9N18573 Acti9 Vigi C120 add-on RCD, 2P, 300 mA, Type A, 125 A, 230-415 V AC, clip-on DIN rail, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"73 mm","Range":"Acti9","Width":"117 mm","title":"A9N18573","Colour":"White","Height":"95 mm","Standards":"EN 61009 IEC/EN 61009-2-1","description":"Vigi C120 - earth leakage add-on block - 2P - 300 mA - class A","9 Mm Pitches":"7","Network type":"AC","Product name":"Acti9 Vigi C120","Mounting mode":"Clip-on","lifecycle_stage":"current","Mounting support":"35 mm symmetrical DIN rail","Pollution degree":"3 conforming to IEC 60947-2","Device short name":"Vigi C120","Network frequency":"50/60 Hz","Poles description":"2P","Tightening torque":"3.5 N.m","[In] rated current":"125 A","Mechanical durability":"20000 cycles","Wire stripping length":"15 mm","Connections - terminals":"Tunnel type terminals 1...35 mm² flexible Tunnel type terminals 1...50 mm² rigid","IP degree of protection":"IP20","Device location in system":"Outgoer Group incomer","Earth-leakage sensitivity":"300 mA","Product or component type":"Add-on residual current device","Electrical connection to mcb":"By screws","[Ui] rated insulation voltage":"500 V AC 50/60 Hz conforming to IEC 60947-1","Earth-leakage protection class":"Type A","[Ue] rated operational voltage":"230...415 V AC 50/60 Hz","Ambient air temperature for storage":"-40...60 °C","Earth-leakage protection time delay":"Instantaneous","Residual current tripping technology":"Voltage independent","Ambient air temperature for operation":"-25...60 °C","[Uimp] rated impulse withstand voltage":"6 kV conforming to IEC 60947-2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/584683c6c2bff3d36bbc251270d0df2d.pdf","sourceUrl":"https://www.se.com/ae/en/product/A9N18573/vigi-c120-earth-leakage-addon-block-2p-300-ma-class-a/"},"ai":{"faq":[{"question":"What is A9N18573's listed depth (73 mm) on this component line?","answer":"The A9N18573 has a depth of 73 mm, a width of 117 mm, and a height of 95 mm."},{"question":"What is A9N18573's listed range (Acti9) on this component line?","answer":"The A9N18573 belongs to the Schneider Electric Acti9 range, specifically the Vigi C120 series of add-on residual current devices."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/A9N18573","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/A9N18573 when reusing this data.
