Description

Smarter 18th Edition Compliant RCBO Consumer Unit – With FuseBox F3023MZ SPD Upgrade

FuseBox F3023MZ

The FuseBox F3023MZ RCBO Consumer Unit With SPD is part of the enhanced FuseBox F3 range. It offers 23 usable ways in a compact double row (double bank) layout, perfect for larger residential installations. By spreading the circuits across two horizontal DIN rails, this board maintains a tidy, accessible layout while keeping installation height more manageable.

The unit includes a 100A double pole main switch, a Type 2 SPD with a pink surge protection enclosure, and a robust fully metal casing. The SPD connects directly to the busbar—no separate MCB required—freeing up valuable DIN space.

🆕 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 – The tail clamp is now fixed directly onto the DIN rail. This offers better cable retention and makes fitting quicker and more secure.
  • Reinforced Grommet Strip – Each unit includes a tougher, more durable grommet strip to protect cables at the point of entry. It’s designed to handle demanding installations without tearing or shifting.

These enhancements make FuseBox F3 boards even more installer-friendly, while staying fully compliant with the 18th Edition Wiring Regulations.


⚡ FuseBox SPD Advantage – Save Space in Your RCBO Consumer Unit

This FuseBox F3 range unit uses a pink SPD enclosure that connects directly to the busbar. No MCB is needed, meaning faster installs and one extra usable way. Visual status indicators show green (safe) and red (fault).


🪛 Use the Right Torque – Stay 18th Edition Compliant

Use a torque screwdriver to install. The included manual shows exact torque values for all terminals, keeping your work safe and fully regulation-compliant.
