It is a 1P+N, 2-pole unit rated at 230 V AC, 50 Hz, with a B-curve tripping characteristic and a 30 mA type A residual-current sensitivity. This is not a bare MCB; the AFDD section monitors for series and parallel arc faults and will disconnect the circuit before the arc energy reaches a level that could ignite adjacent materials — a requirement now mandated by several national wiring regulations for socket circuits in sleeping-accommodation and care facilities. The unit occupies a single 18 mm DIN-rail module (1 MW). Depth is 68.5 mm, installation depth 70 mm. Height is 90 mm. Mounting position is any. The B-curve (tripping characteristic class B) means the magnetic trip activates at 3 to 5 times rated current — for a 20 A unit, that is 60 to 100 A. This is the standard curve for resistive and general-purpose loads in residential and office final circuits; it avoids nuisance tripping on inrush from small motors or capacitive loads that a higher-curve unit would ignore. The 30 mA type A residual-current element catches sinusoidal AC faults and pulsating DC faults up to 6 mA smooth DC — covers most modern electronics with half-wave rectification. The 6 kA breaking capacity (Icn) is the short-circuit rating under EN 60898-1 and IEC 60947-2. In a domestic distribution board with a typical upstream 63 A main switch and a prospective short-circuit current (PSCC) under 6 kA at the board, this unit can interrupt a fault without needing a current-limiting upstream MCB. For industrial panels where the PSCC at the final circuit exceeds 6 kA, this part requires an upstream limiting device. In a multi-circuit board with 12 such units, the cumulative heat (42 W) must be considered in the enclosure thermal design; derating above 40 °C ambient is expected though not explicitly tabulated in this evidence.","metaTitle":"Siemens 5SV6316-6KP20 SENTRON AFDD-RCBO, 20A, B, 30mA, 6kA","metaDescription":"Siemens SENTRON 5SV6316-6KP20 AFDD-RCBO combination, 230V AC, 20A, B-curve, 30mA type A, 6kA, 1 MW wide, active production, sourced to order against RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"68.5 mm","Width":"18 mm","title":"5SV6316-6KP20","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","description":"AFDD-RCBO-combination 230V, 30mA, type A 6kA, 1+N, B, 20A compact (1MW) pigtail","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"1P+N","Number Of Poles":"2","lifecycle_stage":"current","Fastening Method":"DIN rail (REG)","Mounting Position":"any","at AC rated value":"230 V","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Product Designation":"AFDD-RCBO combination","protection class IP":"IP20, with connected protective device and conductors","Overvoltage Category":"III","Design Of The Product":"Compact unit","For Testing Equipment Minimum":"195 V","Number Of Modular Width Units":"1","Position Of Power Supply Cord":"any","Tripping Characteristic Class":"B","according to EN 60898-1 rated value":"6 000 A","according to IEC 60947-2 rated value":"6 000 A","Switching Function Short-Term Delayed":"No","Type Of Voltage Of The Operating Voltage":"AC","Value Range Of The Supply Voltage Frequency":"50Hz","Ambient Temperature With Relative Humidity 95%":"55 °C","Mechanical Service Life (Operating Cycles) Typical":"10 000","Product Extension Installable Supplementary Devices":"Yes","power loss [W] for rated value of the current at AC in hot operating state per pole":"1.75 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/59e761c30b7e7054ec98adfea64b3937.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1268806&mlfb=5SV6316-6KP20"},"ai":{"faq":[{"question":"Will 5SV6316-6KP20 drop into a panel that was specified around 5SY4116-7CV without rewiring?","answer":"Mechanically yes — both are 18 mm wide, 1 MW, DIN-rail mounted.
