It's a Type A-SI (Super Immunised) device with a selective time delay, meaning it's built for circuits where nuisance tripping from high-frequency harmonics or surge currents is a concern — common on supply lines feeding VFDs, UPS systems, or welding equipment. The selective delay coordinates with downstream RCCBs so only the faulted branch trips, keeping the rest of the installation live. The 63 A continuous rating (In) covers the full load of a typical sub-distribution board feeding multiple final circuits — sized for a 3-phase incomer on a residential or light commercial DB. The 300 mA sensitivity is the standard for fire protection (not personal shock protection), so this RCCB goes upstream of the 30 mA devices on socket outlets. The Type A-SI classification handles pulsating DC fault currents and is immunised against unwanted tripping from 50 Hz harmonics and transient surges up to several kA — the SI suffix means it passes the 3 kA surge-withstand test per IEC 61008-1 without tripping. The selective time delay (marked \"S\") introduces a deliberate 40-150 ms delay before tripping, allowing downstream 30 mA RCCBs to clear first; if they don't, this unit backs them up. Tunnel terminals accept 1-35 mm² rigid or 1-25 mm² flexible copper — strip 14 mm, torque to 3.5 N·m. The 18 mm phase-to-phase pitch matches the Acti9 busbar system for a clean feed through a distribution board. IP20 rated for enclosure use only; no washdown rating. ## Standards and environmental Designed and certified to IEC 61008-1, EN 61008-1, and EN 61008-2-1 — the core RCCB standards for residual current protection. Storage range -40 to 85 °C covers most site conditions. Pollution degree 2 (normal, non-condensing). Isolation suitability is confirmed, with a visible contact position indicator and padlocking provision for lockout/tagout.","metaTitle":"Schneider Electric A9N16246 Acti9 xID RCCB, 63A 300mA Type A","metaDescription":"Schneider Electric A9N16246 Acti9 xID RCCB, 63 A rated current, 300 mA earth-leakage sensitivity, Type A-SI Super Immunised, selective time delay. 2P, 230-240 V AC, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"75 mm","Range":"Acti9","Width":"36 mm","Colour":"White","Height":"81 mm","Standards":"IEC 61008-2-1 EN 61008-2-1 EN/IEC 61008-1","9 Mm Pitches":"4","Control type":"Toggle","Network type":"AC","Product name":"Acti9 xID","Mounting mode":"Clip-on","Tropicalisation":"2 conforming to IEC 60068-1","lifecycle_stage":"current","Connection pitch":"18 mm between phases","Local signalling":"ON, OFF, fault trip","Mounting support":"DIN rail","Neutral position":"Left","Pollution degree":"2","Device short name":"xID","Network frequency":"50 Hz","Poles description":"2P","Relative humidity":"95 % at 55 °C","Tightening torque":"3.5 N.m top or bottom","[In] rated current":"63 A","Electrical durability":"4000 cycles","Mechanical durability":"4000 cycles","Wire stripping length":"14 mm for top or bottom connection","Connections - terminals":"Tunnel type terminals (top or bottom) 1...35 mm² rigid Tunnel type terminals (top or bottom) 1...25 mm² flexible","IP degree of protection":"IP20","Earth-leakage sensitivity":"300 mA","Product or component type":"Residual current circuit breaker (RCCB)","Suitability for isolation":"Yes","Contact position indicator":"Yes","Locking options description":"Padlocking device","[Ui] rated insulation voltage":"500 V AC 50 Hz","Earth-leakage protection class":"Type A-SI (Super Immunised)","[Ue] rated operational voltage":"230...240 V AC 50 Hz","Rated breaking and making capacity":"630 A conforming to EN/IEC 61008-1","Ambient air temperature for storage":"-40...85 °C","Earth-leakage protection time delay":"Selective","Ambient air temperature for operation":"-5...40 °C","[Uimp] rated impulse withstand voltage":"6 kV","Comb busbar and distribution block compatibility":"Downside: biconnect"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/in/en/product/A9N16246/acti-9-xid-residual-circuit-breaker-63-a-2p-300ma-class-si-selective/","alternativesUrl":"https://aoctrl.com/api/mcp/products/A9N16246/alternatives.json"},"ai":{"faq":[{"question":"What is the A9N16246 used for?","answer":"It is a 2-pole residual current circuit breaker (RCCB) used for earth-leakage protection in AC networks, typically installed upstream of final sub-circuits in distribution boards.

A standard 30 mA RCCB trips faster and at a lower leakage threshold, so it goes on socket-outlet circuits while this unit protects the upstream feeder."},{"question":"Where can I buy the A9N16246 and get current pricing?","answer":"The part is sourced and quoted to order against an RFQ through independent distribution.
