MCBs are usually located within a consumer unit/fuse box and the relevant information is visible on the front of the MCB when the consumer unit visor is open. Safety is of paramount importance to Electrium. As a responsible manufacturer the company is asking anyone who believes they may have installed (either themselves or through an electrical contractor) any of the above devices within the defined recall period to call the following registration helpline:

Before you call the registration helpline please check if you have an electrical installation certificate or speak with your electrician / contractor to confirm your property is affected. You should then call the customer helpline on:

0844 556 4725

The helpline is open 24 hours a day, seven days a week.

This will enable Electrium to take appropriate action including, where necessary, a free replacement and fitting service.
