ELECTRIUM - PRODUCT RECALL
It has come to our attention that a very small number of Electrium Miniature Circuit Breakers, sold under the brand
names Wylex, Crabtree and Volex are not performing 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 in the following table. All other devices or devices supplied before or after these dates, are unaffected.
