That dual-standard rating covers both residential (EN 60898) and industrial (IEC 60947-2) installations, so the same part works in a distribution board or a control panel. Rated for 50/60 Hz, it handles both common line frequencies without derating. The 72 V DC maximum rating on each pole means it can also be used in DC circuits up to that voltage, though the DC breaking capacity is not separately listed — for DC applications, verify the prospective fault current is within the 10 kA AC rating's equivalent. Snap-on DIN rail mounting, any position — no orientation restrictions. The 72 mm width (4 modular units at 18 mm each) occupies four slots on a standard DIN-rail enclosure. Installation depth is 70 mm, with an overall depth of 76 mm including the front projection. Sealable, halogen-free, and silicon-free construction meets the material restrictions common in clean manufacturing environments and food-grade panels.","metaTitle":"Siemens 5SL4463-7 SENTRON MCB, 4P C 63A 10kA","metaDescription":"Siemens SENTRON 5SL4463-7 miniature circuit breaker, 4-pole, C-curve, 63 A, 400 V AC, 10 kA breaking capacity per EN 60898 & IEC 60947-2.

The 5SL4463-7 adds a fourth pole for switched neutral. Both share the same 400 V AC rating, 10 kA breaking capacity, and 90 mm height. If your panel was designed around a 3-pole breaker and you need switched neutral, the 4-pole unit drops into the same DIN rail but occupies one extra module width (72 mm vs 54 mm)."},{"question":"Where can I buy 5SL4463-7?","answer":"Sourced to order against an RFQ through independent distribution.

It is rated for overvoltage category III and pollution degree 2, which covers fixed-installation distribution boards. The halogen-free and silicon-free construction supports RoHS and REACH compliance, though the specific declarations are issued with the shipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4463-7","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SL4463-7 when reusing this data.
