The 4 MW width means it fills four 18 mm DIN-rail slots — verify busbar and comb-bridge compatibility; a 4-pole busbar is required, not a 3-pole with a jumper. Mounts in any position. Sealable, halogen-free, silicon-free enclosure — relevant for clean-room or marine panel specs where outgassing is restricted. C-curve (5–10× In magnetic trip) suits general-purpose distribution — lighting, socket circuits, small motor branch circuits where inrush is moderate. 6 kA breaking capacity at 400 V AC per EN 60898 is the standard residential/commercial light-industrial rating; for higher fault-current panels (10 kA+), step up to the 5SL4 series. Accepts auxiliary switches, shunt trips, and undervoltage releases (product extension installable supplementary devices = Yes). shows Active status — this is a current-production Siemens SENTRON catalog item. No EOL notice, no LTB window.

The 5SL4363-7 also has a higher per-pole power loss of 5 W vs 4.4 W. They share the same depth (76 mm) and height (90 mm), same C-curve, same mounting position flexibility, and same accessory compatibility. A panel wired for a 3-pole 5SL4363-7 cannot accept the 4-pole 5SL6463-7MB without busbar and width changes."},{"question":"Where can I buy the 5SL6463-7MB and how is it quoted?","answer":"Sourced through independent industrial-automation distribution.
