The 2-pole form factor means it switches both line and neutral on a single-phase circuit, or two phases in a split-phase system — common for lighting sub-circuits or small distribution boards. ## Compliance documentation As a current-production ABB High Performance MCB, the S802S-B25 carries the usual compliance package — CE marking for the European market, RoHS and REACH declarations for material restrictions, and UL/IEC 60947-2 certification for overcurrent protection. The specific certificate numbers and declaration documents are provided with the shipment or on request.","metaTitle":"S802S-B25 ABB 2P 25A Trip Curve B MCB, 50 kA","metaDescription":"ABB S802S-B25 miniature circuit breaker, 2-pole, 25 A, Trip Curve B, 230 VAC, 50 kA interrupting capacity.

Electrically no: the S802S-B25 draws 25 A versus 10 A, and its 50 kA interrupting rating is far higher than the S202M-B10's 6 kA. The panel's bus bar, conductor sizing, and upstream protection must be rated for the higher load and fault current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S802S-B25","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/S802S-B25 when reusing this data.
