Type A detection covers pulsating DC faults, which appear downstream of single-phase rectifiers or switching power supplies. The dual interrupting rating (10 kA per EN 60898, 20 kA per IEC 60947-2) lets you apply it in domestic distribution boards (EN 60898) or industrial sub-distribution (IEC 60947-2) where the prospective fault current is higher. The 1P+N construction switches the neutral, so you get isolation on both poles — important for full disconnection during maintenance. The halogen-free and silicon-free materials reduce toxic smoke and corrosive byproducts in a fault arc event, a consideration for enclosed or populated switchboards. ## Integration notes The IP20 rating applies only when the distribution board is installed and conductors are connected — handle with care during panel assembly. The neutral conductor is switched internally, so no external neutral link is required. The test button requires a minimum of 100 V to operate the test circuit. The 1 kA surge current withstand (8/20 µs waveform) provides some immunity to lightning-induced transients.","metaTitle":"Siemens 5SU1654-6KK25 SENTRON RCBO, 25 A, 300 mA, Type A","metaDescription":"Siemens SENTRON 5SU1654-6KK25 RCBO, 2-pole 1P+N, 25 A, 300 mA residual, Type A, 10 kA (EN 60898) / 20 kA (IEC 60947-2), B-curve, 50 Hz, halogen-free, current lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"77 mm","Width":"36 mm","Height":"90 mm","Maximum":"75 °C","Minimum":"-40 °C","Halogen-Free":"Yes","Silicon-Free":"Yes","Number Of Poles":"2","Type Of Voltage":"AC","lifecycle_stage":"current","Mounting Position":"any","Installation Depth":"70 mm","Product Brand Name":"SENTRON","Degree Of Pollution":"2","Operating Frequency":"50 Hz","Product Designation":"RCBO","acc. to IEC 81346-2":"F","at AC / rated value":"230/240 V","protection class IP":"IP20, if the distribution board is installed, with connected conductors","Overvoltage Category":"III","Design Of The Product":"Instantaneous","Residual Current Type":"A","Number Of Poles / Note":"1P+N","acc. to DIN EN 61346-2":"F","Energy Limitation Class":"3","Weight / With Packaging":"282 g","Number Of Modular Width Units":"2","Tripping Characteristic Class":"B","acc. to EN 60898 / rated value":"10 kA","For Testing Equipment / Minimum":"100 V","Position / Of Power Supply Cord":"Either top or bottom","Number Of Poles / With Protection":"1","acc. to IEC 60947-2 / rated value":"20 kA","Product Feature / Touch Protection":"Yes","Tripping Fault Current / Rated Value":"300 mA","Supply Voltage Frequency / Rated Value":"50 Hz","Influence Of The Surrounding Temperature":"Max. 95% humidity","Surge Current Resistance / At (8/20) μS":"1 kA","operational current / at AC / rated value":"25 A","Product Function / Neutral Conductor Switching":"Yes","Mechanical Service Life (Switching Cycles) / Typical":"10 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$144.29","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/56b2cdfb099f44732c99075d4915a25e.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=306979&mlfb=5SU1654-6KK25","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SU1654-6KK25/alternatives.json"},"ai":{"faq":[{"question":"What is the depth of the 5SU1654-6KK25?","answer":"The overall depth is 77 mm, with an installation depth of 70 mm."},{"question":"What is the width of the 5SU1654-6KK25?","answer":"The width is 36 mm, which corresponds to 2 modular width units on a DIN rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1654-6KK25","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/5SU1654-6KK25 when reusing this data.
