The 55 mm installation depth and 2 width units (about 36 mm on a standard DIN rail) mean it slots into the same cutout as other SENTRON 5SQ breakers — no panel rework if you're swapping a same-series unit.","metaTitle":"Siemens SENTRON 5SQ2570-0KA08 MCB, 2-pole 1P+N, C-curve 8A,","metaDescription":"Siemens SENTRON 5SQ2570-0KA08 miniature circuit breaker, 2-pole 1P+N, C tripping characteristic, 8A rated current, 3kA breaking capacity per EN 60898, 240V AC.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What is the number of poles on 5SQ2570-0KA08?","answer":"It is a 2-pole device wired as 1P+N — one pole switches the line conductor, the other switches the neutral. The neutral pole is switched but not protected against overcurrent."},{"question":"Will 5SQ2570-0KA08 drop into a panel specified for 5SQ2570-2YA04?","answer":"Both share the same 55 mm depth, 2 width units, and SENTRON 5SQ DIN-rail footprint, so the mechanical fit is identical. The electrical difference is the 5SQ2570-2YA04 is a 2-pole (2P) unit rated 4 A at 400 V AC, while this 5SQ2570-0KA08 is 1P+N rated 8 A at 240 V AC. Check your voltage and current requirements before swapping — the wiring scheme (switched neutral vs. solid neutral) and the voltage rating differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2570-0KA08","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/5SQ2570-0KA08 when reusing this data.
