Arc Fault Detection Device AFDD with RCBO | Navitas Circuit Protection
 
Protect what matters with the Navitas AFDD with integrated RCBO — the ultimate safeguard against arc faults, overloads, short circuits and earth leakage in a single compact device.
 
This is not just about compliance. It is about confidence. Engineered for high risk environments, the Navitas AFDD offers advanced arc fault detection combined with Single Pole and Switched Neutral RCBO technology. Every unit is individually tested for performance you can trust.
 
🟢 Arc fault detection built in — catches dangerous faults that standard devices miss
🟢 Switched neutral protection — disconnects both live and neutral during a fault for total isolation
🟢 Individually tested — no batch testing, every device is verified for safety
🟢 Clear fault indicator window — makes diagnostics fast and simple
🟢 Quick test button — proves protection is live in seconds
🟢 Available in B curve from 16A to 40A — ideal for socket and dedicated appliance circuits
🟢 Fully compliant with BS 7671 — designed to meet the latest Amendment 2 requirements
 
Why No 6A or 10A Options?
To ensure the best performance and avoid nuisance tripping, the Navitas AFDD range starts at 16A. This aligns with current guidance around lighting circuit compatibility, where lower current loads can affect AFDD sensitivity. By focusing on higher load circuits, we deliver more reliable protection where it counts.
 
Where AFDDs Matter Most
Arc faults are a major cause of electrical fires. BS 7671 recommends AFDDs in high risk residential environments including HMOs, student housing, care homes and anywhere people sleep. For these installs, AFDDs are not a nice to have — they are essential.
 
The Navitas Advantage
With integrated RCBO protection, no earth fly leads and a compact footprint, the Navitas AFDD is designed for professionals who want faster installs and fewer callbacks. Whether you are fitting out new builds or upgrading existing boards, this is the modern standard in circuit protection.
