The S271C2 is a 2 A breaker, while the S271C1 is a 1 A unit. Choose the rating that matches the protected circuit's full-load current — the physical footprint and mounting are identical."},{"question":"Can the S271C2 be used as a main breaker?","answer":"The S271C2 is a 2 A miniature circuit breaker, sized for final sub-circuits, not as a service-entrance main breaker. Main breakers typically require a higher interrupting rating and current capacity (often 63 A to 125 A). Use it for branch-circuit protection where the load is under 2 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S271C2","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/S271C2 when reusing this data.
