It switches both phase and neutral conductors — the neutral conductor switching function is built in, so you don't need a separate switched neutral bar. Installation depth is 55 mm — shallower than the 70 mm typical of SENTRON's 5SU-series RCBOs, so it leaves more wiring space behind the panel door. IP20 rated, so it's intended for enclosed distribution boards only; no washdown exposure.","metaTitle":"SENTRON 5SQ2270-0KA15 Circuit Breaker, 2-Pole C 15A 400V","metaDescription":"SENTRON 5SQ2270-0KA15 2-pole MCB, C-curve, 15A at 400V AC, 3kA breaking capacity per EN 60898, 50 Hz, IP20.

This is the standard residential and light-commercial fault level; for higher fault currents (10 kA), you'd step up to the 5SL or 5SU series."},{"question":"How do I get current pricing and availability for 5SQ2270-0KA15?","answer":"Pricing and stock levels are confirmed at quote time.

The 5SQ2270-0KA15 is a plain MCB with no RCD, 15 A, 3 kA. They are not drop-in interchangeable; the panel design and protection scheme would need re-evaluation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2270-0KA15","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/5SQ2270-0KA15 when reusing this data.
