Rated 3 out of 5 by from Replacement for a Hager C/B Hi , just be aware this circuit breaker is not a direct replacement for a Hager C/B and not ideal to fit into Hager distribution board. Not a criticism of BG but all circuit breakers are to a BS standard and really should be interchangeable but it appears that they are not.

Rated 4 out of 5 by from 16A breaker Brought to replace volex breaker that had melted due to faulty wiring. Fits DIN rail fine but input connection position does not match Volex breaker so live busbar had to be replaced with wire, only a 2 breaker GOB fortunately Reliability unknown due to short time in service

British General MCB

What's the difference between a Type B and Type C MCB? The British General Garage consumer box comes with a 32amp MCB as standard. I want a 16amp MCB so which one do I order: B or C?
Asked by: R1chieatNabb
Hi R1chieNabb, The different trip classes of MCBs (and RCBOs) are to do with the reaction times for given fault levels, with B curve being the common class for domestic installations (C curve is a little slower and hence tends to be the go-to solution to cure or reduce nuisance tripping incidents being caused by a charge cycle or inrush current in the protected circuit).

I need a 16amp MCB to fit a proteus box, will this fit.?

The ones fitted to the box have type 2 M6 or type 3 M9. on them
Asked by: Absolutelybonkers
Hi Absolutelybonkers, We do not have any technical or testing data for other manufacturers' products, so we cannot make any useful comment on compatibility between their range(s) and our own, nor can we warrant any mixed installation with other manufacturers' products being used alongside our own.

Will these fit in a Crabtree starbreaker

Asked by: Number44
Hi Number44, Most manufacturers' Circuit Protection devices come in at around the same dimensions (give or take a mil) but terminal heights can vary greatly which would lead to undesirable strain on any rigid busbars (which would cause heat spots). A secondary concern is that the 18th edition regulations state that by mixing manufacturers the installer becomes the party responsible for any warranty.

MCBs for solar panels

I need some MCBs for solar panels. Will the ones you sell work with DC as well as AC?
Asked by: NWCharles
Hi NWCharles, There is no need for different MCBs when dealing with a Solar PV system, only RCBOs and RCDs are negatively affected if not of a suitable type, so this device would be OK for up to a 16A (3840W / 3.84kW) system.
