New Product from Crabtree

With the cabling regulation of Crabtree 18th Edition, it presented its single-module arc fault detection device to support its customers. This innovation incorporates 3 elements of technology: MCB, RCD and AFDD. The device prevents fire caused by electricity caused by arc faults and can be applied to existing panels.

Easier. Safer. Faster.

Crabtree announces a single-module arc diagnostic device to prevent electrical fires. As one of Electrium's leading brands, Crabtree has been providing safe electricity solutions in the UK's electricity distribution industry for nearly 100 years.

The single-module arc fault detection device is just one of the solutions made by Crabtree in accordance with Article 18 of the Wiring Directive.

How does it work?

This clever little device detects arc faults and prevents electrical fires in the house.

The single-module arc fault detector uses the AFDD microcontroller and "SIARC" software.

SIARC is a software patented by Siemens that has been able to prove itself in America for years. This software safely distinguishes between arc faults and spark movements of the electrical device, preventing situations that may cause distress.

By combining these two technologies, the device analyzes a wide range of criteria, including current voltage and high-frequency noise, to find a dangerous arc in less than a second.

The AFDD microcontroller also performs many calculations continuously every second to determine if one of the five criteria identified has been violated to detect a fault.

What else can it do?

The device can also perform tasks that MCBs and RCDs can do, and it can detect arc faults that such technologies cannot detect. What's more, this device is half the size of similar devices before it, adapting to any type of panel. It gives you more space and time for other tasks.

The Crabtree single module arc diagnostic device performs an automatic self-test function when it is first started and repeats this test function every 15 hours. It also has a test button that you can use during the initial verification or EICR.

What does the regulation say?

Arc diagnostic devices are currently included in the IET cabling regulations. Wiring regulations 18. According to the article: "Arc fault detection devices can be used in final alternating current circuits to provide extra safety against fire." According to the majority in recent surveys, this technology will help prevent fires.
