The 1P+N configuration means it switches both the phase and the neutral, but only the phase is protected against overcurrent — the neutral pole is switched but not monitored. IEC 60947-2 is the industrial standard; the same 3 kA figure confirms the breaker is also suitable for industrial control panels where the fault level does not exceed that threshold. Overvoltage category 3 (rated impulse withstand) and energy limiting class 3 (fast arc extinction) are consistent with a breaker intended for fixed installations with upstream coordination. IP20 rated for dry indoor enclosures. The neutral pole is switched internally — no separate neutral bar required downstream of the breaker, which simplifies wiring in single-phase boards.","metaTitle":"SENTRON 5SQ2570-0KA05 MCB, 2-pole, C-curve, 5 A, 3 kA","metaDescription":"SENTRON 5SQ2570-0KA05 miniature circuit breaker, 2-pole (1P+N), C tripping characteristic, 5 A rated current, 3 kA breaking capacity per EN 60898 and IEC 60947-2, 240 V AC, 50 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["1-Pole MCB (DIN Rail)"],"specifications":{"Number of poles":"2","Type of voltage":"AC/DC","lifecycle_stage":"current","Installation depth":"55 mm","Product brand name":"SENTRON","Protection class IP":"IP20","Overvoltage category":"3","Energy limiting class":"3","Number of width units":"2","Number of poles / Note":"1P+N","circuit-breaker / Design":"5SQ","Current / at AC / rated value":"5 A","Tripping characteristic class":"C","acc. to EN 60898 / rated value":"3 kA","acc. to IEC 60947-2 / rated value":"3 kA","Supply voltage / at AC / rated value":"240 V","Supply voltage frequency / rated value":"50 Hz","Product function / neutral conductor switching":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=73331&mlfb=5SQ2570-0KA05","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SQ2570-0KA05/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 5SQ2570-0KA05?","answer":"3 kA per both EN 60898 and IEC 60947-2.
