That C-curve means it holds through moderate inrush — motor-start or capacitive loads up to about 5–10× rated current — then trips fast on a hard short. ## DIN-rail footprint and ambient derating The 5SL6463-7 occupies 4 modular units (72 mm) on a standard DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position. At 30 °C it carries the full 63 A; at 40 °C it derates to 59.18 A, at 45 °C to 57.96 A, and at 55 °C to 52.93 A. ## Current production — no obsolescence concern The 5SL6463-7 carries a current lifecycle stage from Siemens. No phase-out notice, no last-time-buy window. For a BOM line that needs this exact 4-pole C 63 A MCB, the supply channel is the standard distribution route — no broker hunt required. ## Panel integration and compliance IP20 with connected conductors. Sealable, halogen-free, silicon-free. Touch protection on the terminals. Neutral conductor is not switched (4-pole without switched neutral). Suitability listed for residential buildings and infrastructure.","metaTitle":"Siemens SENTRON 5SL6463-7 MCB, 4P C 63 A 6 kA","metaDescription":"Siemens SENTRON 5SL6463-7 miniature circuit breaker, 4-pole, C-curve, 63 A, 400 V AC, 6 kA breaking capacity.

The 5SL6463-7 is a 63 A C-curve; the 5SL6550-7BB is a 50 A B-curve. The physical swap is direct — same rail clip, same terminal spacing — but the trip curve and ampacity differ, so verify the branch load and selectivity study before substituting."},{"question":"What compliance documentation does Siemens provide for 5SL6463-7?","answer":"The MCB carries ratings per EN 60898 and IEC 60947-2.
