The 2 A continuous rating governs the protected load's full-load current; any branch drawing over 2 A steady-state will hold the breaker in its thermal region until it trips. ## Deployment Context The S200 series footprint is 2 modules wide (36 mm), so panel fill factor is tight: a 24-way board holds 12 of these. No derating needed for side-by-side mounting at 30 °C ambient; above 40 °C, consult the thermal derating curve in the datasheet.","metaTitle":"ABB S202-D2 2A D Curve Miniature Circuit Breaker, 2-Pole","metaDescription":"ABB S202-D2 miniature circuit breaker, 2 A, Trip Curve D, 2-pole, 277 VAC, 6 kA interrupting.

The difference is trip curve: D (10–20× In) vs C (5–10× In). If the original design called for Curve C (general-purpose), swapping to Curve D may cause the breaker to not trip on a moderate overload that a C curve would catch — verify the load's inrush profile before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S202-D2","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/S202-D2 when reusing this data.
