The 2-pole configuration switches both line conductors simultaneously, which is standard for single-phase 277 V circuits or two legs of a 480Y/277 V system. For BOM-line commitment, the 32 A rating and Curve K characteristic are the two specs that confirm fit against the circuit design. ## Deployment context The compact 2-pole footprint (roughly 36 mm wide for the S200 series) leaves room for adjacent breakers, contactors, or terminal blocks in a crowded panel layout.","metaTitle":"ABB S202MR-K32 Miniature Circuit Breaker, 32 A, 2-Pole, Curv","metaDescription":"ABB S202MR-K32 2-pole MCB, 32 A, Trip Curve K, 277 VAC, 10 kA interrupting capacity.

The difference is the trip curve — Curve K (S202MR-K32) versus Curve B (S202M-B10) — and the interrupting capacity: 10 kA for the K32 versus 6 kA for the B10. If the panel's fault current is under 6 kA and the circuit needs the faster magnetic trip of Curve B, the B10 is the correct fit; for motor or transformer loads with higher inrush, the K32's Curve K characteristic is the better choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S202MR-K32","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/S202MR-K32 when reusing this data.
