He's talking about a 6A RCBO, a B type breaking between 3-5xIn (18-30A) or a C type breaking between 5-10xIn (30-60A).
A C type is generally used for loads with a high inrush current, discharge lighting for example.
Neither will cause a cable to fail during this very short period.
It can be a problem sourcing 6A type B RCBO's from certain manufacturers, Wylex being one example. Recently we had trouble getting anything other than a C type.

Having the same problem with crabtree starbreaker rcbos at the moment. All I can get in 10A or 6A is type c and I dont want to fit a type C. It is an upgrade to a lighitng circuit, split so the bathrooms are on an RCBO and rest of the lighting circuit on a normal 10A type B MCB.
I spoke to my local wholesaler and they said they have never sold a type b 10A or 6A for the starbreaker range and most people use type c.
I can see the need for type c if there is discharge lighitng, or non smps transformers used in some lighting as it would stop any nusance tripping if there is alot on the circuit.
In my case I just need to get a type b to complete a job. At the moment its on a regular breaker on the rcd side of the split load. I want to change it out when I come to finish the job and come to final testing to comply with 17th edd as it wont be good if the rcd trips as the upstaris will be without lighting.
Any one else having this problem?

Until quite recently, most people didn't use RCBOs in houses, so I had always thought the "C" types were popular because they were mostly used in industrial installations.
It's time for that to change! Vote with your wallet!

Nobody can get Type B Wylex RCBO's because we've got them all! 
Bad.
if Zs is too high for a Type C.
Good if Zs is not too high for a Type C.
3kA or 6kA, surely?
