What this MCB carries and where it fits
The 5SY6363-7: The C-curve trips between 5–10× rated current, so it handles moderate inrush from motor starters and transformers without nuisance tripping. Energy limitation class 3 means it clears fast on high faults, limiting let-through energy. With pollution degree 3 and overvoltage category III, it's designed for fixed-installation environments with non-conductive dust and transient surges. Dimensions are three modular width units (54 mm wide) with a depth of 76 mm (installation depth 70 mm). IP20 with connected conductors, sealable, halogen-free, silicon-free. Mounts in any position via the quick assembly system; combined top and bottom terminals simplify wiring in dense panels.
