None - it's a 3 phase RCD
these are easy
It's a 3 phase RCD for industrial/commercial applications. It has no value in a house installation. Even if you use electrical heating in a large TT earthed house and hence have 3 phase, you are unlikely to want a whole house
30mA RCD.To protect multiple circuits with RCD protection without putting an RCD on critial circuits, such as lighting and fridges, you have the following options:

Thanks for advice. I don't really want to replace consumer unit with split one as that involves paying someone to fit it :( Also there are only really
2 circuits I'd want on the RCD side.Must confess I've not come across a RCBO before? Is it a RCD / circuit breaker combo type thing, and do you get them single fitting size for consumer units?
Even better, anyone got links for them in 32 and 16 amps?
It is and you do. However, whether they are available for your specific consumer unit can't be certain.
Christian.
They're also generally 2 units wide - at least all of the ones that I have come across have been. Do you know if it is possible to get single width ones?

It is. However, whether they are available for your specific consumer unit can't be certain.
Example:
At about £40 that doesn't seem too far out of line with the double width ones I've seen in screwfix.
Hager CUs any good? Is it generally better to go for a plastic or a metal CU?
(this CU replacement project is beginning to gain momemtum, ahead of implementation of the new part P regs...)

actually, reading further, the difference between these single module RCBOs and the MK double module RCBOs is that the MK ones are double pole rather than Hager's single pole.
This might have a bearing on the choice of make... take it they're not compatible between makes/CUs?

Although Hager also make a double pole variety in a single module format, can't remember the cat. no. off the top of my head. The problem with trying to find everything on tlc and such like places is that they distribute common items whereas using wholesalers like what I do you generally come across most things when wandering about the stores or thumbing through vast libraries of catalogues!
