AFDD Circuit Breakers & Arc Fault Detection Devices are designed to help reduce the risk of electrical fires caused by arc faults in wiring. This collection brings together a range of AFDDs suitable for modern consumer units, supporting safer electrical installations in domestic and selected commercial settings.

Our range of AFDD circuit breakers is aimed primarily at trade electricians and electrical installers working to current wiring regulations, but can also suit knowledgeable DIYers undertaking permitted work. These arc fault detection devices combine protection against dangerous arcing with other common circuit protection functions, depending on the product selected.

AFDDs are commonly specified for higher-risk areas where damaged cables or loose connections may go unnoticed. Typical applications include residential properties, HMOs, blocks of flats, student accommodation and certain commercial premises. They are often considered for final circuits supplying sockets, sleeping areas, or locations where fire risk mitigation is especially important.

When choosing an AFDD, it is important to consider the circuit rating, number of poles required, and compatibility with the consumer unit you are working with. You should also check whether the device combines arc fault detection with RCD or MCB functionality, depending on your installation design and regulatory requirements.

The AFDDs in this collection are offered in formats intended to integrate with standard distribution boards used in the UK. Product specifications vary by manufacturer and model, so always review the technical details and installation guidance to ensure suitability for the intended circuit and environment.
