Same part, different passport: this is the genuine ABB unit, current lifecycle per the manufacturer, available through independent distribution channels. 6 A is the continuous rated current — it's the load it can carry indefinitely at rated ambient. Trip Curve K has a magnetic trip threshold of roughly 8–12× In, so a 6 A unit will hold a motor starting surge of 48–72 A for a few cycles before the magnetic element trips. That's tighter than Curve D (10–20× In) but looser than Curve C (5–10× In). For a 1-pole breaker, that means it's protecting a single-phase motor or a transformer primary, not a lighting circuit. The 1-pole form factor snaps onto standard DIN rail, so it occupies one module width in the panel. ## Panel integration One-pole width (roughly 17.5 mm). Wire termination is via screw terminals — typical for this class. No special cutout or gland plate needed; it fits in any standard distribution board or sub-panel. For a 6 A motor branch circuit, pair it with a contactor and overload relay downstream; the K curve gives you the coordination window.","metaTitle":"ABB S271-K6 6A 1P DIN Rail MCB, Trip Curve K","metaDescription":"ABB S271-K6 miniature circuit breaker, 6 A, 1-pole, Trip Curve K, DIN rail mount.

Availability and current pricing are confirmed at quote time through our independent distribution network — we source across multiple channels to fill the order."},{"question":"When sourcing S271-K6, what's the closest functional second-source — S201M-C10?","answer":"The S201M-C10 is a 1-pole 10 A breaker with Curve C, not Curve K. It will not drop in as a direct replacement for the S271-K6 without re-evaluating the trip coordination — the magnetic threshold and continuous rating differ. For a 6 A motor circuit, stick with the K curve."},{"question":"What is S271-K6's listed amps (6) on this component line?","answer":"The S271-K6 is rated at 6 A continuous — that's the maximum load current it can carry without tripping under normal conditions."},{"question":"What is S271-K6's listed type (Trip Curve K) on this component line?","answer":"The S271-K6 uses Trip Curve K, which trips magnetically at 8–12× In — suited for motor and transformer loads where inrush is higher than a resistive circuit."},{"question":"Will S271-K6 drop into a panel that was specified around S201M-C10 without rewiring?","answer":"Mechanically yes — both are 1-pole DIN rail breakers with the same footprint. Electrically no — the S201M-C10 is 10 A Curve C, so swapping in a 6 A Curve K changes both the continuous rating and the short-circuit trip threshold. Verify the load and coordination study before substituting."},{"question":"What compliance documentation does this brand provide for S271-K6 (RoHS, REACH, UL, IEC)?","answer":"ABB typically supplies CE, IEC/EN 60898-1, and UL 1077 declarations with the S271-K6 series. RoHS and REACH compliance statements are available on request through the distributor. The specific certifications for each production batch are marked on the side of the breaker."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S271-K6","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/S271-K6 when reusing this data.
