Wylex AFDD Professional Electrician & Installer - Top Product Award 2019

This small device prevents fires

Wylex Arc Fault Detection Devices provide protection against arc faults that can cause electrical fires.
Government statistics show that more than 13,000 electrical fires occur each year in the UK

This single module miniature device uses new technology which means that designers & specifiers can now protect people & property against the risks from electrical faults that would have previously gone undetected. Arc fault detection devices are recommended (by the 18th Edition) as a means of protection against fire caused by arc faults in final circuits.

Wylex AFDD, the ultimate device for protection against overloads, earth leakage, short circuits, and arc faults. Includes switched neutral as standard. All this in an MCB sized footprint.

Single module AFDDs fit in the tightest of spaces because they use smaller consumer units.

Unwanted tripping is avoided via a microprocessor which operates only when dangerous arc fault conditions are present. It continually monitors circuit conditions and carries out a self-test function upon initial power up and every 15 hours thereafter.

Single module AFDD offers 3 levels of fire prevention and protection:

MCB technology

Protection against overcurrent and overheating.

RCD technology

Protection against electric shock

AFDD technology

Protection against arc faults that can cause fires.

#28 Our new AFDD is half the size it used to be.

No need to use a larger Consumer Unit. In fact, a Consumer Unit full of AFDDs is smaller.

#35 71% of electrical professionals agree AFDDs can help prevent electrical fires.

Our devices offer three tiers of fire prevention and protection, including two pole isolation and switched neutral as standard.

#81 Retrofit compatible.  More than just an upgrade

A reduction in electrical fires has been reported in countries where arc fault devices are mandated, including the USA.

Consumer unit


Download your 1 page guide to consumer units and the 18th edition

When looks matter and ease of installation is essential, NM "L Series" consumer units with SPD fitted, make your life easier. With cable entries on all sides and a raised removable interior, there's lots of working space.

#19 MCB sized RCBO for maximum working space

Miniature RCBOs give you lots of extra wiring space in the consumer unit, which makes it easier to manage cables and make your connections.

#57 We make practical, pretty and sleek.

Individual dwellings might not need protection against overvoltages IF the value of the installation and equipment does not justify it. But how much is a typical house full of equipment and appliances worth? Protection from an SPD costs a fraction of the potential loss.

#75 Arc faults cause fires. Wylex AFDDs detect them. (MCBs, RCDs and RCBOs can't).)

Harmful effects of heat or fire may arise from overcurrent, insulation faults, arcs sparks and high temperature particles. Arc fault detection devices are recommended for the purpose of providing additional protection against fires caused by arc faults in 230A AC final circuits. (see chapters 13 & 42)

Surge Protection product
#63 Surge Protection - safeguarding your data and productivity.

Don’t let overvoltages interrupt important public services, SPDs can prevent damage to sensitive equipment and help to maintain availability of important services 24/7 so that we can all benefit from the vital networks in our communities.

The new regulations in 18th edition call for overvoltage protection to be provided in several types of location. Factory fitted SPDs can save you time and money on site.

Individual dwellings might not need protection against overvoltages IF the value of the installation and equipment does not justify it. But how much is a typical house full of equipment and appliances worth? Protection from an SPD costs a fraction of the potential loss.

#34 Surge Protection - Overvoltage protection. We've been doing it for years.

Whether you want off the shelf devices or factory fitted SPDs, Wylex has the solution. From MCCB Panel-boards for commercial applications to Consumer Units for domestic dwellings, talk to us about your needs.

Commercial and Industrial Circuit Protection

Whether it’s an 800 amp Panel-board with up to 18 outgoing ways, including four pole options, or an 800 amp switch fuse for a single sub main circuit. Wylex have the products for your commercial and industrial installation projects.

Wylex reasons #14 Cutting edge Siemens technology inside.

Moulded case circuit breakers with adjustable settings and options for earth leakage, shunt trip, under-voltage release, and more. The new Wylex MCCBs can easily accommodate accessories for control and monitoring applications.

#60 We design and build bespoke solutions for unique commercial projects.

It’s easy to select and create your own off the shelf power distribution solutions with our panel board selection chart, but if you prefer it we can custom build to your client specification. It’s what we do.

Our UK based R&D teams create installer friendly solutions like compact enclosures that fit into smaller spaces than before while also delivering more power than before. Designed tested and built in the UK with Siemens circuit protection technology inside.

Miniature RCBO product

The new Miniature RCBO

With switched neutral as standard

Total isolation of faulty circuits without interrupting power on any other circuits, a safer way to wait for the emergency electrician.

#25 Totally Chapter 31 compliant.

Using switched neutral RCBOs fully complies with Chapter 31 requirements for - division of the installation, avoiding danger, minimising inconvenience, preventing unwanted tripping and permits safe testing and maintenance.

#21 Our miniature RCBO fully isolates faulty circuits for maximum safety.

Switching off a Wylex miniature RCBO isolates the live and neutral, which more than complies with Health & Safety standards for safe working if equipment needs changing or additions are being made.

Ratings from 6A to 40A to cater for heavy loads e.g. showers and cookers as well as lighting and general power circuits. There's even a 25A rating.
