Occupies 2 width units (36 mm) on a DIN rail, with an installation depth of 55 mm — shallow enough to clear most enclosure back panels without crowding. IP20 finger-safe terminals suit enclosed distribution boards; no special sealing for washdown or outdoor exposure. The neutral conductor is switched internally (2-pole switching), so this breaker isolates both phase and neutral on fault or manual disconnect — a requirement in many regional wiring codes for final subcircuits.","metaTitle":"Siemens SENTRON 5SQ2270-0KA10 MCB, 2-pole C 10A 400V AC/DC","metaDescription":"Siemens SENTRON 5SQ2270-0KA10 miniature circuit breaker, 2-pole, C-curve, 10A, 400V AC, 3kA breaking capacity per EN 60898.

The 5SQ2270-0KA10 is a plain MCB with no RCD, lower 3 kA breaking capacity, and 10 A rating. They are not drop-in substitutes; the RCBO requires neutral connection and occupies a different width."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2270-0KA10","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/5SQ2270-0KA10 when reusing this data.
