The interrupting capacity is 6 kA at 277 VAC and 10 kA at 250 VDC. That 6 kA AC figure is standard for downstream distribution in a panel fed by a larger upstream device — it clears a bolted fault within its rating without welding the contacts, but needs coordination with the branch feeder if the available fault current exceeds 6 kA. Single-pole footprint saves one module width over a 2-pole equivalent — relevant when filling a sub-distribution board or a control panel where every 18 mm slot counts.","metaTitle":"ABB S201MUC-K60 MCB, 1P, 60 A, Curve K, 277 VAC","metaDescription":"ABB S201MUC-K60 S200MUC series MCB, 1-pole, 60 A, Trip Curve K, 277 VAC / 250 VDC. 6 kA interrupting rating AC.

Availability and current pricing are confirmed at quote time."},{"question":"What is the closest functional alternative to S201MUC-K60?","answer":"The S201MUC-K2 is the same 1-pole S200MUC platform with the same Curve K characteristic and interrupting ratings, but rated 2 A instead of 60 A. It shares the same physical footprint and DIN-rail mount, so it drops into the same panel position without rewiring — but the amp rating is completely different, so it is not a functional substitute for a 60 A circuit."},{"question":"What is S201MUC-K60's listed amps?","answer":"60 A. That is the continuous current rating at 40 °C ambient — the breaker carries 60 A indefinitely without tripping."},{"question":"What does Trip Curve K mean on S201MUC-K60?","answer":"Curve K trips magnetically at 8 to 12 times rated current. For the 60 A version, that means the magnetic trip coil operates between 480 A and 720 A — designed for motor and inductive loads with moderate inrush, not for transformer or capacitor banks that need a higher multiple."},{"question":"Will S201MUC-K60 fit in a panel built for S201MUC-K2?","answer":"Yes — same 1-pole S200MUC housing, same DIN-rail mount, same terminal spacing. It occupies the same panel slot and connects the same way. The only difference is the amp rating and trip calibration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S201MUC-K60","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/S201MUC-K60 when reusing this data.
