Rated 4 out of 5 by from Great price Great price and to have these available from screwfix (pity had to wait next day for it to be ready for collection). Cosmetically different to the original breakers (seems a bit cheaper to me) and the only thing I would like these to have is the red and green indicators for on/off. Works perrfectly.

Rated 5 out of 5 by from MCB Cheap and cheerful this is a great replacement or addition to the fusebox. easy to fit and with only a cosmetic difference a direct replacement for the original units fitted! the only downside is it is a next day item.

Rated 5 out of 5 by from MCB Just the job I have a Crabtree starbraker consumer unit and needed to add an additional circuit. Fitted perfect although the exterior profile is slightly different to the original MCB’s fitted. Works and fitted with out any bother and excellent value. Impressed that screwfix can order this into store as it’s not listed in the catalogue

Rated 5 out of 5 by from Available next day. Told by my Electrician to get this item, and recommended Screwfix. This particular unit is only available to Order, Next Day, but that was no problem, and it was ready the next day as promised. Job done.

Hi, are these MCB’s the same fitment & spec as the version with the switch positioned in the middle vertically? Thanks.

Asked by: whatever4
Hello. These MCBs will fit any Crabtree unit that has a Starbreaker plug in busbar system first manufactured in the late 1980’s – they are fully compatible with this busbar system and consumer units. Thank you for your interest in our Crabtree brand.

MCB removal

Hi. stupid question for some, how do you actually remove an individual mcb from the "rail".It doesn't look like they just pull out like the plug in type. Any info. appreciated. Thanks, Steve.
Asked by: willintolearn
A small lug under the bottom edge of the MCB. Using a flat blade screw driver, prise the lug down a few mm and the bottom of the MCB will come off the rail then just unhook the top. ENSURE POWER IS ISOLATED BEFOREHAND. If unsure, call an electrician!
