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.

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.
