Description

The Fusebox F3021MZ (Replaces Fusebox F2020MX) is a 21-way RCBO consumer unit equipped with a 100A main switch and a Type 2 Surge Protection Device (SPD). Designed to guard against transient over-voltages and lightning strikes, it features Fusebox’s advanced SPD1MT2 device, which connects directly to the busbar—eliminating the need for a miniature circuit breaker and enhancing both safety and ease of installation.

Designed for Streamlined Installation

Like with the rest of the Fusebox line, the Fusebox F3021MZ is installer-friendly with a variety of 20–40mm knockouts for flexible cabling options.

Built to Last

Fully compliant with BS EN 61439-3 standard, rated IP2XC for electrical safety and constructed from rust-resistant galvanised steel, this unit combines durability with trusted performance.
