Rated at 6 A at 30 °C, it derates to 5.55 A at 40 °C, 5.37 A at 45 °C, 5.22 A at 50 °C, 5.01 A at 55 °C, and 4.8 A at 60 °C. That derating curve is the real-world rating — if your panel ambient runs 50 °C, you're sizing for 5.22 A continuous, not 6 A. Overvoltage category 3 and pollution degree 3 mean it's rated for fixed-installation panels where transients and conductive dust are expected — standard for industrial control cabinets. The 2-pole design includes neutral conductor switching (the 'N' in the description), so it breaks both phase and neutral when tripped — useful where you need full isolation on a single-phase or split-phase circuit. Installation depth is 55 mm — fits standard distribution boards and sub-panels without crowding.","metaTitle":"Siemens SENTRON 5SQ2270-2YA06 MCB, 2-pole C 6 A, 3 kA","metaDescription":"Siemens SENTRON 5SQ2270-2YA06 miniature circuit breaker, 2-pole, C-curve 6 A, 3 kA breaking capacity per EN 60898, 400 V AC.

The only difference is the current rating — 6 A vs 4 A. If the circuit load is within 6 A, it's a direct mechanical and electrical swap; no rewiring needed."},{"question":"What compliance documentation does this brand provide for 5SQ2270-2YA06?","answer":"As a Siemens SENTRON product, the 5SQ2270-2YA06 carries CE marking for the European market and is designed to EN 60898. Standard documentation includes the declaration of conformity, datasheet, and installation instructions. RoHS and REACH compliance is standard for current-production SENTRON devices."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2270-2YA06","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/5SQ2270-2YA06 when reusing this data.
