Curve C means the magnetic trip fires at 5 to 10 times the rated current (200 to 400 A), so it handles moderate inrush from small motors, transformers, or capacitor banks without popping on startup. The 277 VAC rating is line-to-neutral for 277/480 Y systems common in North American commercial lighting panels. On the DC side, 60 VDC at 10 kA interrupting capacity covers control power supplies and battery circuits — a useful edge over the AC-only breakers in this footprint.","metaTitle":"S201M-C40 Miniature Circuit Breaker, 40A C Curve, 1-Pole, DI","metaDescription":"S201M-C40 MCB, 40 A, Trip Curve C, 1-pole, 277 VAC / 60 VDC, 6 kA interrupting rating.

The AC rating is standard for branch-circuit protection in commercial panels; the DC rating is higher than typical for this class, which helps when the breaker sees battery or rectified supplies."},{"question":"Will the S201M-C40 drop into a panel built for the S201M-C10?","answer":"Yes — same S200M family, same 1-pole DIN-rail footprint, same 277 VAC / 60 VDC voltage ratings. The only difference is the 40 A thermal rating versus 10 A. No rewiring of the bus or mounting hardware needed; just verify the branch circuit conductor is sized for 40 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S201M-C40","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/S201M-C40 when reusing this data.
