What would you record in the "type" box on the electrical certificate?

Datasheet suggests MCCB, if I'm understanding what exactly you are asking, or do you mean trip charectaristic; type a ac etc?

Yes, so if it were a 60898 it would be a type B, C or D. But as it's a 60947 I'm not sure what to put in the type box

I don't think MCCB have as well defined characteristics as the B/C/D sort of type for MCB.

Looking at the data sheet along it says 16A thermal and 600A magnetic so (assuming they are fixed) that is a ratio of 37.5 and more than a D-type MCB of 10-20 In instantaneous rating!

Unlike 60898 devices 60947-2 devices are not categorised so you enter NA for the type. To ensure disconnection times are met you need to consult manufacturers data as no single figure can be put across all manufacturers.
