Mounts on standard DIN rail, so it drops into any existing distribution board without adapter plates.","metaTitle":"ABB S201MR-K10 MCB, 1P, 10A, Curve K, 10kA","metaDescription":"ABB S201MR-K10 miniature circuit breaker, 1-pole, 10 A, Trip Curve K, 277 VAC, 10 kA interrupting rating.

That's higher than a Curve C (5–10×) but lower than Curve Z (2–4×). It's designed to ride through the inrush of inductive loads like small motors, transformers, and solenoid valves while still clearing a hard short fast enough to protect the cable."},{"question":"What is the interrupting rating of the S201MR-K10?","answer":"It carries a 10 kA interrupting rating at 277 VAC. That's the maximum fault current the breaker can safely interrupt without welding its contacts or rupturing the arc chamber. For most commercial panelboards fed by a 50–100 kVA transformer, 10 kA is adequate at the branch level — but verify the available fault current at the point of installation against the panel SCCR."},{"question":"Where can I buy the S201MR-K10?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
