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.
