It snaps onto standard 35 mm DIN rail inside a distribution board or control panel, protecting downstream wiring and loads against overcurrent and short circuits. The C-curve characteristic means it holds through moderate inrush (typical of motor starters and transformers) and trips on sustained overload at 5–10× rated current — a good fit for mixed resistive-inductive loads out here in the grease.","metaTitle":"ABB S263-C63 DIN Rail MCB, 63A C-Curve Circuit Breaker","metaDescription":"ABB S263-C63 DIN rail miniature circuit breaker, 63A C-curve.

The key difference is the trip curve and current rating — the S263-C63 is a 63 A C-curve, while the S273-K6A is a 6 A K-curve (a steeper magnetic trip for semiconductor protection). Verify the required curve and ampacity for your load before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S263-C63","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/S263-C63 when reusing this data.
