The 36 mm width (2 width units) and 76 mm depth leave room for adjacent breakers and busbars in a crowded enclosure. Terminal accepts solid or stranded copper from 0.75 to 25 mm²; tighten to 2.5–3 N·m. Mounting position is unrestricted — any orientation works, which simplifies panel layout. IP20 with connected conductors means it is protected against finger contact but not washdown; keep it inside a closed panel.","metaTitle":"Siemens 5SL6240-7BB SENTRON MCB, 2P C-40A 6kA 400V","metaDescription":"Siemens 5SL6240-7BB SENTRON miniature circuit breaker, 2-pole, C-curve 40 A, 6 kA per EN 60898, 400 V AC.

Submit an RFQ; availability and current pricing are confirmed at quote time."},{"question":"Will 5SL6240-7BB drop into a panel that was specified around 5SL6563-7BB without rewiring?","answer":"Both are 2-pole SENTRON 5SL6 breakers with the same 36 mm width and 76 mm depth, so the mechanical fit is identical. The difference is the tripping curve: 5SL6240-7BB is C-curve (40 A), while 5SL6563-7BB is a different curve/rating. Verify the curve and ampacity match your circuit before swapping — the footprint is the same, but the protection characteristic must suit the load."},{"question":"What is 5SL6240-7BB's listed depth (76 mm) on this component line?","answer":"The depth is 76 mm, with an installation depth of 70 mm.
