It carries the F1 tripping characteristic, rated 1 A at 230 V AC (50/60 Hz) and 60 V DC, with an interrupting capacity of 3 kA AC per IEC 60934. That F1 curve is a fast-acting, high-sensitivity trip designed for semiconductor and sensitive electronic loads where a standard B or C curve would let through too much energy before opening. Snaps onto DIN rail (35 mm) — one modular width unit at 18 mm wide, so it takes up a single slot in the enclosure. Mounts horizontal or vertical; no derating penalty for orientation. The IP20 finger-safe terminals accept the usual panel wiring, and the auxiliary switch (1P+AS) gives you a remote status signal without needing a separate aux block. Vibration-resistant per IEC 60068-2-6, so it holds up on machine-mounted subpanels. The sealable option (tamper-evident cover) is useful for installations requiring lockout or inspection seals.","metaTitle":"Siemens 5SY1701-2 SENTRON Device Protection Switch, 1A F1, 1","metaDescription":"Siemens 5SY1701-2 SENTRON device circuit breaker, 1-pole with auxiliary switch NO, F1 characteristic, 1A, 230V AC/60V DC, 3kA Icn, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["1-Pole MCB (DIN Rail)"],"specifications":{"Depth":"76 mm","Width":"18 mm","title":"5SY1701-2","Height":"90 mm","Maximum":"70 °C","Minimum":"-40 °C","Sealable":"Yes","Standard":"IEC / DIN EN 60934, UL1077","description":"Device circuit breaker 1-pole with auxiliary switch NO contact Characteristic F1 1A 230 V AC 50/60 Hz 60 V DC Icn 3 kA AC according to IEC 60934","Halogen-Free":"Yes","Silicon-Free":"Yes","Design Of Pole":"1P+AS","Number Of Poles":"1","lifecycle_stage":"current","Fastening Method":"DIN rail","Mounting Position":"Horizontal/vertical","at AC rated value":"230 V","at DC rated value":"60 V","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Product Designation":"Device protection switch","protection class IP":"IP20","Overvoltage Category":"III","Combined Terminal Top":"No","Combined Terminal Bottom":"No","Neutral Conductor Switching":"No","Number Of Modular Width Units":"1","Position Of Power Supply Cord":"Any","Tripping Characteristic Class":"F1","Influence Of The Surrounding Temperature":"30 °C @ 85%rF; 60 °C @ 20%rF\"","Type Of Voltage Of The Operating Voltage":"AC/DC","Value Range Of The Supply Voltage Frequency":"50/60 Hz","operating voltage at DC rated value maximum":"72 V","with single-phase operation at AC rated value":"250 V","vibration resistance according to IEC 60068-2-6":"Yes","Mechanical Service Life (Operating Cycles) Typical":"6 000","Product Extension Installable Supplementary Devices":"Yes","power loss [W] for rated value of the current at AC in hot operating state per pole":"2.3 W"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/170fed6b32e099883d38c53aa3a6b05c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=802779&mlfb=5SY1701-2"},"ai":{"faq":[{"question":"What is the closest functional second-source for 5SY1701-2?","answer":"The 5SY1701-2 is a 1-pole F1 curve breaker with an integrated auxiliary switch. A close functional peer is the 5SY4116-7CV, which is also a 1-pole device protection switch but with a different characteristic and current rating — verify the trip curve and amp rating before substituting. The 5SY1701-2 will drop into the same DIN-rail footprint (18 mm width) as the 5SY4116-7CV without rewiring, but the F1 curve and 1 A rating are specific to the 5SY1701-2."},{"question":"What compliance documentation does Siemens provide for 5SY1701-2?","answer":"The 5SY1701-2 is designed to IEC / DIN EN 60934 and UL1077 standards.
