FuseBox Consumer Units

Shop FuseBox consumer units (fuse boards) for modern UK installations, with options including RCBO consumer units, dual RCD boards, main switch boards and configurations with SPD protection. FuseBox boards are popular with electricians for straightforward installation layouts and a strong range of device and kit options.

Choose a board based on the number of ways you need, the protection approach (RCBO vs dual RCD), and whether your spec calls for SPD protection or outdoor/IP-rated enclosures. For the best fit, use the filters and check the product datasheet for included devices, configuration details and compatibility.

Looking for individual FuseBox protective devices instead of a complete board? Visit our FuseBox Shop to browse RCBOs, MCBs, RCDs, AFDDs, SPDs and accessories.
