Both are 1-pole DIN-rail K-curve breakers. Key difference: the S201MUC-K2 is rated 2 A and carries a higher voltage ceiling (277 VAC / 250 VDC) with a lower interrupting capacity (6 kA AC / 10 kA DC). The S801U-K15 delivers 15 A at 240 VAC with a stronger 25 kAIC — so it fits higher-fault panels and heavier branch loads. Footprint (1 module width) and rail mount are identical; no rewiring needed if the panel was specced around the S201MUC-K2, as long as the ampacity and voltage ratings match the application.","metaTitle":"S801U-K15 15A 1-Pole K-Curve DIN Rail Breaker","metaDescription":"ABB S801U-K15 DIN rail breaker, 15A, 1-pole, Trip Curve K, 240VAC, 25kAIC.
