Mounting is standard DIN rail, so it clips directly into a 35 mm rail inside a panel or enclosure. The 2-pole form factor occupies two module widths — plan your DIN rail fill accordingly. The 110 VDC rating covers control-circuit applications on DC buses, though the AC side at 277 VAC is the primary duty for most lighting or motor branch circuits. ## How the S802UE-K20 compares to the S202M-B10 The closest functional peer is the S202M-B10. Both are 2-pole, DIN-rail MCBs with a 6 kA interrupting rating at 277 VAC. The critical difference is the trip curve: the S802UE-K20 uses Curve D, while the S202M-B10 uses Curve B.","metaTitle":"S802UE-K20 ABB MCB 2P Trip Curve D 13A 277VAC","metaDescription":"ABB S802UE-K20 miniature circuit breaker, 2-pole, Trip Curve D, 13 A, 277 VAC, 6 kA interrupting rating, DIN rail mount.

However, verify that its 13 A rating and Trip Curve D match your load's inrush and coordination requirements, since the S202M-B10 uses Curve B and is rated 10 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S802UE-K20","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/S802UE-K20 when reusing this data.
