Its 10 kA breaking capacity is certified to both EN 60898 and IEC 60947-2, meaning it can safely interrupt fault currents up to 10 kA without upstream device intervention — a key figure for panel selectivity studies. ## Active production and sourcing posture The 5SL4306-7 accepts add-on auxiliary switches, shunt trips, and alarm contacts via the SENTRON accessory system, so a single panel stock keeps spares common across multiple circuit configurations. Occupies 3 modular width units (54 mm) on a DIN rail, with a 70 mm installation depth and 76 mm overall depth. Mounting position is unrestricted — install it in any orientation inside the enclosure. Rated for ambient temperatures from -40 °C to 75 °C, with IP20 protection (finger-safe when conductors are connected).","metaTitle":"Siemens 5SL4306-7 3-Pole MCB, C-Curve, 6A, 10kA","metaDescription":"Siemens 5SL4306-7 SENTRON miniature circuit breaker, 3-pole, 6A, C-curve, 10kA breaking capacity per EN 60898 & IEC 60947-2.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["3-Pole MCB (DIN Rail)"],"specifications":{"Depth":"76 mm","Width":"54 mm","title":"5SL4306-7","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 400 V 10kA, 3-pole, C, 6A","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"3P","Number Of Poles":"3","lifecycle_stage":"current","Mounting Position":"any","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Product Designation":"Miniature circuit breaker","protection class IP":"IP20, with connected conductors","Overvoltage Category":"III","Energy Limitation Class":"3","Suitability For Operation":"Residential buildings/infrastructure","at DC rated value maximum":"72 V","Number Of Modular Width Units":"3","Tripping Characteristic Class":"C","supply voltage at AC rated value":"400 V","according to EN 60898 rated value":"10 kA","according to IEC 60947-2 rated value":"10 kA","Type Of Voltage Of The Operating Voltage":"AC","with multi-phase operation at AC maximum":"440 V","Value Range Of The Supply Voltage Frequency":"50/60 Hz","with multi-phase operation at AC rated value":"440 V","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":"1.6 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.86","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5b69e2d7e81e2f42b38e770e8cc909de.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=356031&mlfb=5SL4306-7"},"ai":{"faq":[{"question":"Is the 5SL4306-7 suitable for 3-phase applications?","answer":"Yes — it's a 3-pole breaker rated 400 V AC with multi-phase operation up to 440 V AC, making it a direct fit for three-phase 400/440 V line circuits."},{"question":"Is the 5SL4306-7 suitable for DC applications?","answer":"Its DC rating is limited to 72 V maximum.
