The FuseBox circuit protection range of metal consumer units and protection devices offers flexible, versatile solutions for electrical installations.

The range comprises of 6, 10, 14, 18, 22, 28 and 36 module enclosures in single and double bank variations, with or without T2 surge protection fitted.

These include: Main switch incomer, Dual tariff, RCD incomer, Dual RCD, Garage units and EV charger units.

The FuseBox T2 surge protection consumer units provide protection against transient over voltages and the secondary effects of lightning strikes with a Type 1 SPD coming soon to complement the range.

Design features include:

T2 surge protection
Earth and neutral terminal bars at the top
Removable and raised DIN rail
Round knock-outs on all faces
Extra height for RCBOs
1mm electro-galvanised steel (zinc)
RAL 9001 powder coated finish
Tail clamp (ACCF)
Circuit identification labels
Captive screws on front cover
IP20XC
BS EN61439-3

Why Choose FuseBox AFDD? | Complete Guide

AFDD/RCBOs are being primarily installed in new builds on final circuits, particularly in high-risk residential buildings, Houses of Multiple Occupancy (HMOs), purpose-built student accommodation, and care homes, for single-phase circuits supplying socket-outlets up to 32A. An AFDD detects dangerous arc faults that traditional breakers might miss, while the integrated RCBO protects against earth faults and overcurrents, thus providing comprehensive protection against fire hazards in these specific locations.
