Snap it onto a DIN rail in the panel — 17.5 mm wide, standard 1-module footprint. The 17.5 mm width leaves room for adjacent modules in a crowded enclosure. The black actuator is sealable and carries I/O marking for lockout/tagout. Strip length for the screw terminals is standard for the class; torque to the value printed on the device face.","metaTitle":"ABB S201P-K4 MCB 1P K 4A 277VAC, 10 kA","metaDescription":"ABB S201P-K4 miniature circuit breaker, 1-pole, K-curve, 4 A, 277 VAC, 10 kA interrupting.

The difference is the trip curve: S201M-C3 is a C-curve (magnetic trip 5–10x In) at 3 A; the S201P-K4 is a K-curve at 4 A. If the panel's load and coordination study call for a K-curve at 4 A, the S201P-K4 is the correct fit — it will not drop in as a direct substitute for a C-curve without verifying the upstream selectivity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S201P-K4","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/S201P-K4 when reusing this data.
