Electrium Miniature Circuit Breakers (MCBs)

13 October 2010


A very small number of Electrium MCBs, sold under the brand names Wylex, Crabtree (Loadstar only) and Volex are not perfroming to the required characteristics. This can lead to a potential risk of burning, in a small number of installations.


The affected MCBs were supplied from April 2009 to February 2010 and are listed above. All other devices are unaffected. Devices supplied outside these dates are unaffected.

What To Do

Electrium have put in place a free retrofit of replacement parts in affected premises.

The retrofit programme is ongonig. Electrium continues to monitor and assess the risk and the number of problems experienced remains very small. However, as the problem involves in a very few cases a risk of burning, this is being taken seriously. Please therefore ensure you fully cooperate with their efforts.

This work must be carried out by a qualified competent electrician, under no circumstances should the general public attempt any aspect of this work.

If you have purchased or installed any of the product listed above, between the dates shown, please visit the dedicated web page for assistance:
