Crabtree's New Miniature AFDD Means a Big Leap for Electrical Safety

Crabtree New Miniature AFDD

Installers can now improve electrical safety, without any extra effort with the Starbreaker combined AFDD-RCBO, this innovative new product integrates arc fault detection with RCD and MCB capability in a revolutionary single DIN module, delivering maximum safety in the minimum footprint. Fully catering for the requirements and recommendations of the 18th Edition Wiring Regulations.

The Starbreaker Mini AFDD provides an extra layer of protection while also helping future-proof installations against ever-changing regulations. Recognised as a ‘significant risk’ in the 18th Edition IET Wiring Regulations, arcing is typically caused by poorly made or failing connections or failing insulation in AC 230V final circuits. While RCDs and MCBs protect against overcurrent, short circuit and earth leakage protection, they are unable to detect arcing, leaving a potential gap in the safety provision.

Until recently installers have had no access to AFDDs. Early models were two modules wide and took up too much space to be used in the already crowded consumer unit – which limited uptake. The new Starbreaker Mini AFDD overcomes this barrier by combining all three layers of protection in one DIN module.

Using digital technology to constantly monitor circuit conditions, the Starbreaker Mini AFDD can distinguish between ‘operational sparking”- for example, in washing machines and vacuum cleaner motors - and abnormal activity that could denote a potentially dangerous event.  Complying fully with the requirements of BS 7671, this single module AFDD is a two-pole switching device which will totally isolate any faulty circuit or appliance, ensuring complete peace of mind for installers, homeowners and investors.

As an additional benefit, the new Starbreaker Mini AFDD-RCBO is an easy to fit ‘plug and play’ option that can be installed into any appropriate Starbreaker consumer unit, without the need for special assembly or new busbars. Explains Dave Enefer, Devices Product Manager at Crabtree. “Whatever the age of the Starbreaker unit, the new Mini slots easily into place, so it’s equally suitable for new builds, upgrades and retrofits to provide additional protection.”

Bringing three levels of safety in one easy-fit single module, Crabtree’s Starbreaker Mini AFDD represents a major step forward in electrical safety.
