The Trip Curve K characteristic trips magnetically between 8 and 12 times rated current (so 8–12 A for this 1 A unit), which is designed for loads with moderate inrush like small transformers, solenoid valves, or motor starters where a standard C-curve might nuisance-trip on startup. The 1 A rating makes it a fine spare for control transformers or instrumentation circuits drawing under an amp — keep one on the shelf for that low-current feeder that always seems to fail on a Friday. ## DIN rail integration Single-pole width (roughly 17.5 mm per pole) means it takes up one module space in the enclosure. For a panel with mixed C-curve and K-curve breakers, the S201P-K1 shares the same footprint and busbar pitch as the rest of the S200 series — no adapter needed.","metaTitle":"S201P-K1 1A 1-Pole Trip Curve K MCB, 277 VAC, 10 kA","metaDescription":"S201P-K1 miniature circuit breaker, 1 A, 1-pole, Trip Curve K, 277 VAC, 10 kA interrupting rating.

But the S203-C10 is a 3-pole, 10 A, C-curve unit; the S201P-K1 is 1-pole, 1 A, K-curve. They are not functional substitutes for the same circuit. The S201P-K1 fits the same rail and enclosure but serves a different load (low-current inductive vs general-purpose 10 A)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S201P-K1","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/S201P-K1 when reusing this data.
