Sealable design (padlockable toggle) lets you lock out a circuit for maintenance without a separate lockout device. Combined top and bottom terminals simplify busbar and outgoing wiring; neutral conductor is not switched (solid neutral bar passes through). Rated for ambient temperatures from -40 °C to +75 °C, with humidity limits up to 95 % at 55 °C, derating to 35 % at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — tough enough for machine-mounted panels near rotating equipment. Halogen-free and silicon-free construction, overvoltage category II, pollution degree 2, energy limitation class 3. Complies with IEC/EN 60898-2 and UL1077 — the UL listing matters for North American panel builds that require recognized components.","metaTitle":"Siemens 5SY5432-6 SENTRON MCB, 4P, B-curve, 10 kA, 400 V AC","metaDescription":"Siemens SENTRON 5SY5432-6 miniature circuit breaker, 4-pole, B-curve, 10 kA per IEC 60898, 15 kA per IEC 60947-2, 400 V AC / 880 V DC, universal current, active production, quoted","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["4-Pole MCB (DIN Rail)"],"specifications":{"Depth":"76 mm","Width":"72 mm","title":"5SY5432-6","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Sealable":"Yes","Standard":"IEC / EN 60898-2, UL1077","description":"Circuit breaker Universal current 880 V DC 400 V AC 10kA, 4-pole, B, 32A max. 1000 V DC","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"4P","Number Of Poles":"4","lifecycle_stage":"current","Fastening Method":"Quick assembly system","Mounting Position":"any","at AC rated value":"400 V","at DC rated value":"880 V","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":"II","Combined Terminal Top":"Yes","Energy Limitation Class":"3","Combined Terminal Bottom":"Yes","Suitability For Operation":"universal current","Neutral Conductor Switching":"No","Number Of Modular Width Units":"4","Position Of Power Supply Cord":"AC as required, observe DC polarity","Tripping Characteristic Class":"B","at DC according to EN 60898-2":"10 kA","according to EN 60898 rated value":"10 kA","Influence Of The Surrounding Temperature":"max. 95% to 55°C, max. 55% to 70°C, max. 35% to 75°C","Type Of Voltage Of The Operating Voltage":"AC/DC","at DC according to IEC 60947-2 rated value":"15 kA","Value Range Of The Supply Voltage Frequency":"50/60 Hz","operating voltage at DC rated value maximum":"1 000 V","with multi-phase operation at AC rated value":"440 V","with single-phase operation at AC rated value":"440 V","vibration resistance according to IEC 60068-2-6":"±1mm at 5 to 25Hz; 50m/s² at 25 to 150Hz","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":"2.6 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0cb74cd8c92356fb0804c5445547f452.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=351511&mlfb=5SY5432-6"},"ai":{"faq":[{"question":"Who supplies 5SY5432-6 and how is it quoted for volume purchases?","answer":"Sourced and quoted to order through independent distribution channels.
