The WME04/MS100 Main Switch Consumer Unit is a compact 4-module metal enclosure supplied with a 100A main switch incomer. Designed for small domestic installs, garages, and outbuildings, it provides 2 usable ways ready for population with MCBs or RCBOs. Finished in white powder-coated steel, with raised DIN rails and multiple knockouts for flexible cable entry, it’s a simple but fully compliant base board.
