Above 40 °C the curve steps down: 15.5 A at 45 °C, 15 A at 50 °C, 14.5 A at 55 °C, and 14.1 A at 60 °C. DC rating is limited to 60 V maximum — this is an AC-optimized breaker. For DC branch circuits above 60 V you need a different pole configuration or a DC-rated series. Vibration resistance is specified at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz (4-second dwell) — it holds up on a machine frame or near a motor without nuisance tripping from vibration. The 18 mm width (1 MW) means it fits a standard 18 mm-per-pole grid; you can pack multiple poles side by side without odd spacing. The part is sealable, halogen-free, and silicon-free — useful for food/beverage or clean-room panels where outgassing or contamination must be controlled.","metaTitle":"Siemens 5SJ4116-8HG40 SENTRON MCB, 16 A, 1P, 18 mm","metaDescription":"Siemens SENTRON 5SJ4116-8HG40 miniature circuit breaker, 16 A rated at 30-40 °C, 1-pole, 18 mm wide, DIN rail mount, IP20, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["1-Pole MCB (DIN Rail)"],"specifications":{"Depth":"70 mm","Width":"18 mm","title":"5SJ4116-8HG40","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 240 V 14kA, 1-pole, D, 16A, D=70 mm according to UL 489, equal polarity","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"1P","Number Of Poles":"1","lifecycle_stage":"current","Fastening Method":"on standard mounting rail","Mounting Position":"any","at AC rated value":"16 A","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","at 30 °C rated value":"16 A","at 40 °C rated value":"16 A","at 45 °C rated value":"15.5 A","at 50 °C rated value":"15 A","at 55 °C rated value":"14.5 A","at 60 °C rated value":"14.1 A","Tunnel Terminals Bottom":"No","according to EN 61346-2":"F","Combined Terminal Bottom":"Yes","according to IEC 81346-2":"F","Suitability For Operation":"Mechanical engineering / industry","at DC rated value maximum":"60 V","Neutral Conductor Switching":"No","Number Of Modular Width Units":"1","Position Of Power Supply Cord":"Any","Tripping Characteristic Class":"D","supply voltage at AC rated value":"400 V","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)","Type Of Voltage Of The Operating Voltage":"AC/DC","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 (Switching 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":"2.1 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$30.48 – $84.04","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/21d3ee32c9369264f1f257f040522bc1.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=391909&mlfb=5SJ4116-8HG40"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4116-8HG40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SJ4116-8HG40 when reusing this data.
