The difference is the trip curve (D vs C) and the amp rating (63 A vs 40 A) — verify the branch-circuit load and coordination study accept the higher inrush tolerance of Curve D before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S201-D63","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/S201-D63 when reusing this data.
