🔧 FuseBox SPD Without MCB: The Smartest Upgrade for Faster Installs

Table of contents

The FuseBox SPD Without MCB is a major step forward in board design. It’s now available in the new F3 FuseBox Consumer Units. This upgrade includes a Type 2 SPD that connects directly to the busbar — no MCB needed.

You can also browse our full range of FuseBox Consumer Units, including older models, to find the right board for any job.

This change marks a big moment for the UK electrical industry. FuseBox, known for setting standards, is now leading the move to cleaner, faster SPD setups.

⚡ What’s New in the F3 FuseBox Consumer Units

The F3 range features the SPD1MT2 — a compact, single-module Type 2 SPD. It installs directly onto the busbar. No MCB needed. That means faster fitting, less wiring, and more space inside the board.

For years, the FuseBox SPD + MCB combo was standard. But with this update, the F3 FuseBox Consumer Units now offer the same trusted quality — with fewer parts and a much faster setup.

🔌 FuseBox SPD Without MCB – What It Means for Installers

Most electricians followed the FuseBox way: install the SPD with an MCB. Even when other brands removed the MCB, many stuck with what they knew.

Now, FuseBox has made the move itself. Their new Type 2 SPD connects straight to the busbar. It’s safe, fast, and space-saving. No more wasting space or wiring a breaker just for the SPD. You save time, gear, and effort — all while using the brand you trust.

🔌 How the F3 FuseBox Consumer Units Simplify SPD Installations

FuseBox has made SPD installs easier than ever. With the F3 range, there’s no need for a separate MCB. The SPD1MT2 clicks straight into the board.

You get:

  • Faster installs
  • Less wiring
  • One more usable way
  • A cleaner, simpler layout

This setup is smart, safe, and backed by the FuseBox name.

❓ Frequently Asked Questions (FAQ)

A FuseBox SPD Without MCB is a surge protection device that connects directly to the busbar inside the consumer unit. It does not require a separate miniature circuit breaker (MCB), saving space and simplifying installation.

The new F3 FuseBox Consumer Units come with this SPD setup. These units include the SPD1MT2 Type 2 SPD, pre-fitted or available as an option across the full F3 FuseBox range.

🔹 Can I still use the older FuseBox SPD with MCB?

Yes, of course! There is nothing wrong with using the older FuseBox SPD setup that includes an MCB. It’s still fully compliant and safe. The new FuseBox SPD Without MCB is simply a more compact and efficient option — but both setups are valid depending on your preference or install needs.
