Rated breaking capacity: 15 kA and 10 kA. ## Environmental and mechanical resilience The breaker is sealable, which allows locking the cover to prevent unauthorized access in safety-critical circuits – a common requirement in industrial machine disconnect panels. It is halogen-free and silicon-free, suitable for environments where outgassing or contamination can affect nearby electronics (e.g., clean rooms or medical equipment). The design accepts copper conductors with a tightening torque of 3.5 Nm (31 lb·in) – compatible with typical 60/75 °C rated wire. Combined (screw + clamp) terminals on both top and bottom simplify wiring and reduce the number of terminal types on the panel.","metaTitle":"Siemens 5SJ4160-6HG40 1-Pole MCB, B-Curve 60A, 15kA IEC, DIN Rail","metaDescription":"Siemens SENTRON 5SJ4160-6HG40 miniature circuit breaker – 1-pole, B-curve, 60 A, rated 400 V AC and 60 V DC, 15 kA breaking capacity per IEC 60947-2, 70 mm depth, sealable, halogen","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":"5SJ4160-6HG40","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","description":"Miniature circuit breaker 240 V 14kA, 1-pole, B, 60A, 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":"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":"1","Position Of Power Supply Cord":"Any","Tripping Characteristic Class":"B","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":"6.5 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$112.06","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2db0e8a2471831669f79aa54a2190add.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=263567&mlfb=5SJ4160-6HG40"},"ai":{"faq":[{"question":"Does 5SJ4160-6HG40 fit as a direct replacement for existing Siemens MCB with same form factor and B-curve?","answer":"Yes. The 5SJ4160-6HG40 is a 1-pole, 18 mm wide, B-curve breaker. It mounts on standard DIN rail, so it replaces any similarly rated Siemens MCB (e.g., 5SX or 5SN series) with the same trip characteristics and amperage, provided the voltage and breaking capacity requirements match."},{"question":"Does 5SJ4160-6HG40 comply with IEC 60947-2 for industrial applications at 15 kA breaking capacity?","answer":"Yes. The breaker is rated 15 kA per IEC 60947-2, making it suitable for industrial networks with higher fault currents. It also carries a 10 kA rating per EN 60898 for residential/commercial applications."},{"question":"What is the maximum DC voltage rating of 5SJ4160-6HG40 for use in photovoltaic combiner boxes?","answer":"The maximum DC voltage rating is 60 V. This limits its use to low-voltage PV arrays (e.g., small off-grid systems) where the string voltage does not exceed 60 V. For higher DC voltages, a different MCB with a higher DC rating is needed."},{"question":"Is 5SJ4160-6HG40 sealable to prevent unauthorized access in safety-critical circuits?","answer":"Yes. The breaker is explicitly marked as sealable, allowing a locking mechanism to be applied to prevent tampering or unauthorized resetting – a requirement in many industrial safety circuits."},{"question":"Are the halogen-free and silicon-free properties of 5SJ4160-6HG40 verified by third-party certification?","answer":"The specifications list halogen-free and silicon-free as part of the product design. These claims are based on the manufacturer's material declaration; verify with Siemens if internal compliance documentation or third-party certification is required for your specific application."},{"question":"What are the exact width and depth for DIN rail mounting to ensure proper spacing in a panel?","answer":"Width is 18 mm (1 modular unit) and depth is 70 mm. Height is 90 mm. These dimensions match standard DIN-rail MCB footprints, allowing straightforward spacing calculations in your panel layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4160-6HG40","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/5SJ4160-6HG40 when reusing this data.
