Rated 5 out of 5 by Replacement MCBs I wished to replace existing fuses in old consumer unit with circuit breakers. Just replace fuse base plate with new plate using one screw and plug in new MCB. Very simple and easy. 1 Apr 2015

Rated 5 out of 5 by Product spec The lower product spec is incorrect - the mcb's are 3kA rated and not 6 as suggested 19 Oct 2010
Rated 5 out of 5 by Great Buy I bought this for my mum as she had a standard fuse box and always struggled if a fuse blew. It is really easy to fit and now I have peace of mind knowing she can easily reset the MCB. Great delivery time too. 10 Jan 2010
