Description

The FuseBox F3031MZ is a high-capacity 29-way consumer unit featuring a 100A main switch and factory-fitted Type 2 surge protection device (SPD). Part of the next-generation F3 Series, it delivers enhanced installation flexibility, improved cable management, and SPD integration that does not consume a usable way thanks to FuseBox’s single-module direct-to-busbar SPD technology.

Designed for larger domestic installations and small commercial applications, the F3031MZ provides a reliable, regulation-ready platform for multi-circuit distribution with additional mechanical improvements that electricians have come to expect from the F3 range.

High-Capacity Double-Bank Layout

This model offers a 29-way configuration arranged as 15/16 ways across a double-bank chassis, giving contractors generous space for larger distribution designs without increasing the footprint unnecessarily.

The F3031MZ benefits from several installer-focused upgrades introduced in the FuseBox F3 Series:

Direct-to-busbar single-module SPD — no MCB required, freeing an additional usable way

Upgraded reinforced grommet strip for improved cable protection and feed-through durability

Improved internal layout for cleaner wiring and better cable management

These enhancements streamline installation while maintaining all the trusted FuseBox build quality that installers rely on.
