The closest peer in the SENTRON family is the 5SL4363-7 — same depth (76 mm) and height (90 mm), same C curve, same 32 A rating. Two differences matter: the 5SL4363-7 is 3-pole (no switched neutral), so it occupies 3 MW units (54 mm) instead of 4. If your panel needs a switched neutral and the fault level stays under 6 kA, the 5SL6632-7 is the correct fit. If the fault level exceeds 6 kA or you don't need neutral switching, the 5SL4363-7 is the higher-rated alternative — but verify the neutral bar arrangement; a 3P breaker leaves the neutral solid.
Panel integration — DIN rail, sealable, halogen-free
Four modular width units (72 mm) — plan the rail space accordingly. Halogen-free and silicon-free materials reduce toxic smoke and silicone outgassing in enclosed panels — relevant for food processing or electronics assembly lines. Installation depth 70 mm — leaves clearance behind the DIN rail for wiring.
