Sourcing and fit
This MCB is specified for residential buildings and infrastructure per the manufacturer's suitability listing. It is a standard SENTRON 5SL-series device, so it shares the same DIN-rail footprint, busbar comb, and terminal accessories as the rest of the 5SL family. If you are replacing a 5SL4363-7 (a 63 A D-curve 3-pole), the 5SL4316-8 drops into the same panel slot with the same wiring — just match the amp rating to your load.
