Smarter 18th Edition Compliant RCBO Consumer Unit – Now with Direct-Busbar SPD

FuseBox F3031MZ

The FuseBox F3031MZ RCBO Consumer Unit With SPD delivers premium circuit protection for larger installations. It features 31 usable outgoing ways, split across a double row (dual-bank) DIN rail layout—making the wiring layout neater and reducing board height.

It includes a 100A double pole main switch, a direct-to-busbar SPD housed in FuseBox’s updated pink surge protection enclosure, and a full metal case finished in RAL 9001. This SPD design removes the need for an additional MCB, freeing up extra space and simplifying installation.

What’s New in the FuseBox F3 Consumer Unit Range?

The most significant upgrade in the FuseBox F3 range is the new single module pink SPD that connects directly to the busbar — meaning no separate MCB is required. This not only saves a usable outgoing way, but also makes wiring faster and neater.

Other improvements include:

  • DIN Rail-Mounted Tail Clamp – Securely attached to the rail for faster, safer cable fitting
  • Reinforced Grommet Strip – Provides strong, lasting cable protection at all entry points

Torque Accuracy = Safer Install

For compliance with BS7671, always use a torque screwdriver and follow the values listed in the included user manual. This ensures secure, long-lasting terminal connections.
