IP20 with conductors connected; IP40 in the handle range. That means it is protected against solid objects >12.5 mm (finger-safe) in normal operation, but not against dust ingress or water. Suitable for clean, dry indoor panels — not for washdown or outdoor enclosures without a higher-rated outer cabinet. Halogen-free and silicon-free construction, which matters for clean-room or sensitive electronics environments where outgassing can cause contact corrosion or optical haze. Vibration resistance tested at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds — typical for industrial machinery mounted on a panel wall. Overvoltage category 3 per IEC 60664, meaning it is designed for fixed installations where transient overvoltages are controlled by the upstream distribution — standard for a sub-distribution board or final branch circuit.","metaTitle":"Siemens 5SJ4150-6HG40 SENTRON MCB, 1-pole B-curve 50 A, 10/1","metaDescription":"Siemens 5SJ4150-6HG40 SENTRON miniature circuit breaker, 1-pole, B characteristic, 50 A rated current, 10 kA (EN 60898) / 15 kA (IEC 60947-2), 400 V AC, 60 V DC, DIN-rail mount, ac","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":"5SJ4150-6HG40","Height":"90 mm","Sealable":"Yes","Rated Value":"50 Hz","description":"Miniature circuit breaker 240 V 14kA, 1-pole, B, 50 A, D=70 mm according to UL 489, equal polarity","Halogen-Free":"Yes","Silicon-Free":"Yes","Mounting type":"on standard mounting rail","During Storage":"-40 ... +75 °C","Number of poles":"1","Type of voltage":"AC/DC","lifecycle_stage":"current","Mounting position":"any","Installation depth":"70 mm","Product brand name":"SENTRON","Ambient temperature":"-25 ... +55 °C","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","Number of width units":"1","Number of poles / Note":"1P","acc. to DIN EN 61346-2":"F","acc. to DIN EN 81346-2":"F","Product function / Note":"Terminal tightening torque for Cu, 60/75°C; 3.5Nm/31lb.in","Tunnel terminals bottom":"No","Combined Terminal Bottom":"Yes","circuit-breaker / Design":"5SJ4","Suitability for operation":"Mechanical engineering / industry","Current / at AC / rated value":"50 A","Tripping characteristic class":"B","at DC / rated value / maximum":"60 V","acc. to EN 60898 / rated value":"10 kA","Position / of power supply cord":"Any","acc. to IEC 60947-2 / rated value":"15 kA","Product feature / Touch protection":"Yes","Supply voltage / at AC / rated value":"400 V","Installation environment regarding EMC":"Suitable for environment B (immunity to interference not applicable)","Influence of the surrounding temperature":"max. 95% humidity","Insulation voltage / at AC / rated value":"440 V","Vibration resistance / acc. to IEC 60068-2-6":"50 m/s² at 25 to 150Hz and 60m/s² at 35Hz (4sec)","Product function / neutral conductor switching":"No","Mechanical service life (switching cycles) / typical":"20 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$81.84","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a9fc441c34ba752d714db532dc6217cb.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=352002&mlfb=5SJ4150-6HG40"},"ai":{"faq":[{"question":"What are the key ratings for this MCB?","answer":"1-pole, B-curve, 50 A at 400 V AC, 60 V DC max.
