For purely resistive loads or long cable runs where inrush is minimal, a B-curve (3× to 5× In) provides faster fault clearing; for high-inrush loads like large motors or welding equipment, a D-curve (10× to 20× In) avoids nuisance tripping. ## Active Lifecycle and Sourcing Reality IP20 protection (with connected conductors) and overvoltage category III cover the typical distribution board environment. The MCB is sealable, halogen-free, and silicon-free — relevant for installations requiring low-corrosion or clean-room compliance.","metaTitle":"Siemens 5SL4325-7 3-Pole MCB, 25A, C-Curve, 10kA, 400V AC","metaDescription":"Siemens SENTRON 5SL4325-7 miniature circuit breaker: 3-pole, C-curve, 25 A, 400 V AC, 10 kA 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":"5SL4325-7","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 400 V 10kA, 3-pole, C, 25A","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":"2.3 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$182.46","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b97409499536e89ee77516dc7ad97276.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=294901&mlfb=5SL4325-7"},"ai":{"faq":[{"question":"What is the breaking capacity of the Siemens 5SL4325-7?","answer":"The 5SL4325-7 has a rated breaking capacity of 10 kA per EN 60898 and IEC 60947-2 at 400 V AC."},{"question":"Is the Siemens 5SL4325-7 a 3-pole MCB?","answer":"Yes, it is a 3-pole miniature circuit breaker (3P design) rated for 400 V AC three-phase systems."},{"question":"What is the difference between C-curve and B-curve in MCBs like the 5SL4325-7?","answer":"The C-curve (5× to 10× In) is designed for loads with moderate inrush current — motors, transformers, fluorescent lighting.
