The S281-K10's K-curve and 480 VAC rating give it a wider voltage envelope and better coordination on motor circuits. If your panel was specified around the S201M-C10, the S281-K10 will not drop into the same footprint without checking the voltage rating and trip coordination — same rail, same pole count, but different curve and voltage class.","metaTitle":"S281-K10 ABB 1P 10A Trip Curve K MCB, 480VAC DIN Rail","metaDescription":"S281-K10 ABB 1-pole miniature circuit breaker, 10 A, Trip Curve K, 480 VAC, DIN rail mount.

However, the S281-K10 is rated 480 VAC versus the S201M-C10's 277 VAC, and uses a K-curve instead of a C-curve. Check voltage rating and trip coordination before substituting — no rewiring needed if the circuit voltage is within the S281-K10's rating and the trip curve is acceptable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S281-K10","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/S281-K10 when reusing this data.
