Rated insulation voltage (Ui) is 440 V AC, with an overvoltage category of 3 and pollution degree 3 — this means it's rated for fixed installations in industrial environments where transient overvoltages are expected. The DC rating of 60 V covers common control-circuit voltages. The 10 kA (EN 60898) and 15 kA (IEC 60947-2) ratings give the panel designer headroom for selectivity studies; the higher IEC number is the one to use for industrial coordination. Vibration resistance is specified at 50 m/s² over 25 to 150 Hz and 60 m/s² at 35 Hz for 4 seconds — sufficient for mounting on machine frames or near rotating equipment.","metaTitle":"Siemens 5SJ4208-7HG41 SENTRON MCB, 2P C-curve 10kA, 70mm dep","metaDescription":"Siemens 5SJ4208-7HG41 SENTRON miniature circuit breaker, 2-pole, C characteristic, 10 kA per EN 60898, 15 kA per IEC 60947-2, 400 V AC, 60 V DC, 70 mm depth, 36 mm width, IP20, cur","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["2-Pole MCB (DIN Rail)"],"specifications":{"Depth":"70 mm","Width":"36 mm","title":"5SJ4208-7HG41","Height":"110 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 240 V 14kA, 2-pole, C, 8A, D=70 mm according to UL 489","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"2P","Number Of Poles":"2","lifecycle_stage":"current","Fastening Method":"on standard mounting rail","Mounting Position":"any","at AC rated value":"400 V","at DC rated value":"60 V","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"3","Product Designation":"Miniature circuit breakers","protection class IP":"IP20, with connected conductors, IP 40 in the handle range","Overvoltage Category":"3","Tunnel Terminals Top":"No","Vibration Resistance":"50 m/s² at 25 to 150Hz and 60m/s² at 35Hz (4sec)","Combined Terminal Top":"Yes","Design Of The Product":"Miniature circuit-breaker 5SJ4","Product Function Note":"Terminal tightening torque for Cu, 60/75°C; 3.5Nm/31lb.in","Tunnel Terminals Bottom":"No","Combined Terminal Bottom":"Yes","Suitability For Operation":"Mechanical engineering / industry","at DC rated value maximum":"60 V","Neutral Conductor Switching":"No","Number Of Modular Width Units":"2","Position Of Power Supply Cord":"Any","Tripping Characteristic Class":"C","according to EN 60898 rated value":"10 kA","Ambient Temperature During Operation":"max. 95% humidity","Supply Voltage Frequency Rated Value":"50 Hz","according to IEC 60947-2 rated value":"15 kA","installation environment regarding EMC":"Suitable for environment B (immunity to interference not applicable)","insulation voltage (Ui) at AC rated value":"440 V","Value Range Of The Supply Voltage Frequency":"50/60 Hz","vibration resistance according to IEC 60068-2-6":"±1 mm at 5 to 25 Hz; 50 m/s² at 25 to 150 Hz","Mechanical Service Life (Operating Cycles) Typical":"10 000","Product Extension Installable Supplementary Devices":"Yes","Tightening Torque With Screw-Type Terminals Maximum":"3.5 N·m","power loss [W] for rated value of the current at AC in hot operating state per pole":"2.6 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$91.44","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/9ca3d90aaa4033e550b78738350a6684.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=223066&mlfb=5SJ4208-7HG41"},"ai":{"faq":[{"question":"Where can I buy 5SJ4208-7HG41 and get a price?","answer":"This part is sourced to order through our independent distribution channel.
