MCBs


Miniature circuit breakers, or MCBs, are switches that will turn off electrical circuits during an overload of current. Browse a large variety of MCBs from trusted manufacturers for your electrical circuit needs. We have 1-, 2-, 3- and 4-pole MCBs with a current rating of 1A to 63A, so regardless of your requirements, you will find the miniature circuit breaker you need right here. For any queries about our MCB range, speak to a member of the team at sales@cpc.co.uk or 03447 880088.
