The 6 A continuous rating means this breaker carries 6 amps steady without nuisance tripping — sized for a small motor, a transformer primary, or a lighting circuit drawing under that load. The Trip Curve K gives a fast magnetic trip (typically 8–12x In) that catches inductive inrush without false trips on motor start or transformer energization. One-pole width (about 17.5 mm) leaves room for adjacent breakers or accessories in the same row. Wire termination accepts copper conductors up to the standard cross-section for a 6 A circuit; torque to the value printed on the breaker side.","metaTitle":"ABB S201MR-K6 1-Pole 6A Type K MCB, 277V AC, 10kA, DIN Rail","metaDescription":"ABB S201MR-K6 miniature circuit breaker, 6 A, Trip Curve K, 1-pole, 277 V AC, 10 kA interrupting rating.

Both are 1-pole Type K breakers on DIN rail, so the S201MR-K6 drops into the same panel footprint without rewiring — just verify the load current and available fault current match the higher ratings."},{"question":"Where can I buy S201MR-K6?","answer":"The S201MR-K6 is sourced and quoted to order against an RFQ through our independent distribution network.
