The 5SL6463-7MB: Depth is 76 mm, height 90 mm, width 72 mm (4 MW). 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).
