Arc Fault Detection Devices (AFDDs) are specialist protective devices designed to detect dangerous electrical arc faults that standard MCBs and RCDs cannot identify. An arc fault detection device monitors the electrical waveform and disconnects supply when a hazardous arc is detected – helping to prevent electrical fires.
All AFDD RCBOs supplied by Power & Data UK are BS EN 62606 compliant, fully aligned with 18th Edition Amendment 2, and UK stocked for next-day delivery.
Quick answer: An AFDD RCBO combines arc fault detection, overload protection, short-circuit protection and residual current protection in one device.

An AFDD monitors circuit behaviour for signatures associated with dangerous arc faults. The products in this range also combine residual-current and overcurrent protection, but selection still depends on the circuit scope, current rating, trip curve, RCD type and compatibility with the distribution board.
Select the current rating from the circuit design and conductor capacity. The range covers common final-circuit ratings rather than one universal AFDD size.
An AFDD RCBO brings arc-fault detection, overcurrent protection and residual-current protection into one device for an individual circuit.
Requirements and recommendations depend on the premises and circuit covered by the current edition of BS 7671. Confirm the installation category and design basis.
