At 277 VAC it delivers a 10 kA interrupting capacity, enough for most panelboard fault levels downstream of a 22 kA main. Snaps onto standard DIN rail; occupies two pole widths in the enclosure. ## Selectivity and coordination The K-curve on this 25 A breaker is the deciding factor for motor branch circuits and inductive loads — it holds through the 8–12× inrush region where a C-curve would trip. Compared to a C-curve sibling at the same 25 A frame, the S202P-K25 gives you wider headroom for starting currents on pumps, compressors, and small conveyors. The 10 kA SCCR at 277 VAC coordinates cleanly with a 22 kA main upstream, provided the let-through energy of the main does not exceed the breaker's rated short-circuit capacity. ## Panel integration DIN rail mount, 2-pole width. Strip length 8 mm. Occupies standard 36 mm per pole on the rail — plan fill factor accordingly in the enclosure layout.","metaTitle":"S202P-K25 Miniature Circuit Breaker 2P K-Curve 25A 277V","metaDescription":"ABB S202P-K25 2-pole MCB, K-curve, 25 A, 277 VAC, 10 kA interrupting.
